New Grower - Looking For Advice

Hey guys,

So after many shady encounters I decided to start growing my own smoke. A friend of a friend had some cuttings (im not even sure on the strain if i'm honest) I'm currently doing it in a built in wardrobe and i'm now into flowering stage.

I have 2 plants under a 600W - 90,000 lumen light, and Im now feeding them A, B and Big Bud.

Now i've had no help at all throughout my grow and i've had to try to do things on myself, I topped the plants during veg (watched a youtube video) and everything seemed to be working out okay.

My plants are in 25L plant pots, with canna soil & coco ball topping.

Ive been feeding them once a day around 1.5L of water with 3ml of A & B + 6ml of BB.

Im finding that my bigger leaves are turning yellow and dying. Ive read so much information on why it could be but I thought if i could post some photos somebody with more expertise could point me in the right direction as after all the time spent i would hate to see my plants start to die now.

So to my questions.

How often should i be watering/feeding my plants? Im around 4 weeks into flowering stage.
How much feed should i be giving them? A,B, Bigbud (and should i have anything else for them?)
Why are the leaves turning yellow and dying? (I think its lack of nitrogen from what ive read but how would i go about adding more nitrogen to my plants if that's the case?)

My humidity is around 45% and my temps fluctuate between 73F during the day and 82F during the night (i have them on 12/12 and start at 4.30pm until 4.30am.

Ive attached some photos (sorry about the quality they're from an older mobile phone)


Thanks a bunch in advance to anybody willing to spend abit of time to help me out,

New Grower,
Rick

how long has it been in flower under 12/12 ? leaves fat or skinny ?
larger older leaves naturally stop photosynthesizing as the plant matures. If you feed a complete system, and your other controls are correct, then the plant isnt experiencing unnatural deficiencies.
 
Hey Chemphlegm thanks for the fast reply! :)

So its been in flower for 4 weeks, 12/12 since the start of flowering (hope thats right!?)

Its mainly the feeding that im struggling with as i literally have 0 idea how much im supposed to be feeding them.

Its normal for the big leafs to yellow in mid flower. The plant is "emptying the wearhouses it built" you feed some N in flower but not much. My advise to you is to not buy Advanced nutrients again, they are ok nutrients, thats all. They arnt very clear on what they are and they spend a lot on marketing and pass the expense on to the customer. For chemical nutrients i can recommend the general hydroponics Micro as a great nitrogen source. Its very cheap, and just a tiny bit per gallon is perfect. I feed as the plant asks, for example you start with tapwater, then a few waterings into the plants life add the smallest ammount possible to the water, then a little more next time etc etc. Alternate between feed days and plain water days. After uncreasing nutrients maybe do a linger period of straight water days. If the leafs are yellowing, GH micro will make them green again. If the leafs get dark green and thick looking, dont add micro for a week or longer. When you get into flowering add the flowering nutrients the same way, very little at first, then more. Give the plants half veg and half flower nutrients 2 weeks before flower, and 2 weeks into flower. Dont give nitrogen past 2 weeks into flower until you know that you should, i dont commonly add nitrogen past 2 weeks, it can hurt the flower cycle. Generally less is more, the plant wont need much, but the more you give it that doesnt hurt it the bigger you might yield, maybe. When tge edges of the leafs burn then your just right, back off a few days, the continue. If whole leafs are burning, you fucked up, remember what you did, and dont do that. If leafs are twisting or folding, same story, back off. Thats all you need to know in a nutshell, with the exeption of a flower nutrient recommendation, there are several good ones, just look for stuff thats fairly priced and straightforward. If they spent a ton on marketing and have a high pricetag just move on. Supernatural brand is good, GH is good, lots of the organic brands are good, not sure what you have easy access to, but... ive used maybe 10 diff lineups and AN is lower middle road IMO.

If your using Canna nutrients then check out Cannagrowguide for the feeding schedule. If your not using Canna then just google your brands feeding schedule.

I don't think 1.5l is enough water for a 25 ltr pot. I use 18ltr pots and it takes about 4ltr of water to feed each.
You want some run off to come out of the bottom. You don't have to feed them every day in 25ltr pots, I don't imagine that they are that big to need a feed every day. If you don't have some run off then salts can build up and cause problems.

I'm not sure what you mean by canna soil and coco balls. Canna soil is called Canna Terra, Canna Coco is different but ive never seen coco balls unless you mean hydroton which is clay balls.

I grow in Coco and you can water it daily but you must have some run off from the bottom. I personally like to water every 48 hours. I used to water every 3 days. The watering comes down to how big the root system is and how quickly they drink that water up. In soil you want to water until some comes out of the bottom and rewater when the top inch has dried out, or when the pot feels light. You can water more often in coco and not have any problems.

http://www.canna-uk.com/growguide for a feeding schedule.

If your using canna nutrients then 3ml for 1.5ltr of water is on the low side, you can nearly double that amount. Doesn't hurt to slightly underfeed but too little and your plant will feed off itself starting at the lower big leaf and work up.

If your using canna products then I would get a bottle of pk13/14 for a boost of phosphorous and potassium around the 5th week of flower. Big bud is ok but your plant still needs the extra P and K , Plus its good to have a bottle of cal/mag in coco.

You have come to the right place for info. Everything you could possibly need to know is available on this forum and there are some amazing growers with a wealth of experience.

Good luck with the plants and welcome to RIU
 
Hey Corey & Growfun ! Thanks for the epic replies, really helpful :D

Yeah im using Canna Terra & Clay Balls (my bad) TBH i felt like i was under-watering them as after 3 hours under the light the soil was feeling dry and i think you may be right with starting from the big leafs, I'll double the water I'm putting in and hopefully that will keep them going.

I should have put im using 3ml of A and 3ml of B (6ml in total) and 6ml of Big Bud.

I do happen to have "Jungle Juice Micro & Bloom" but i read a bad review somewhere so was scared to feed them to it. Which do you think i would be better using?

Also with regards to the pk13/14 do you suggest using this for the rest of the flowering cycle or just for the 5th week?.

They're a decent size (wouldnt say massive but for my first grow i'm quite impressed) its just im now worried they're going to die as all the bigger leaves are dying and turning yellow.

Somebody i know IRL Told me to cut the big leaves off but from what ive read that can cause stress? Should i be doing that this late into flowering?.

Really loving the forum so far. I see myself being educated a fair bit from here and hopefully eventually learn enough to pass along abit of information to friends.

When the leaf is depleted nutrient stores just snap it off the stalk with your fingers. Once you learn the trick its fast and easy, clean. I havent used any nutrients that didnt work, they should all carry you threw no problem, kinda comes down to preferance and cost. I just advise people not to fall for gimicks marketed to stoners
 
Will snapping it off cause problems at all? I'm reading mixed reviews on google, some saying it'll make me have to wait a week extra, and others saying it'll be fine.. o_O

Ive been growing 7+ years now, if your snapping dead leafs or nutrient depleted leafs your helping it by removing dead plant matter. Dead plant matter leads to problems. Mildew, bugs, bad news. Dont buy into the "no till" crap stuff too while we're talking about dead plant matter. Dont be lazy, clean up your grow area. There will not be a ammount of co2 released to make it worth it, and you add nutrients already, so there is no reason to invite mold.

Dont remove leafs that are not dead/nutrient depleted, and do not defoliate.

Soon as you learn how to properly handle your plants that whole "2 weeks of stress" goes right out the window. Youll learn how to handle during a transplant. Dirt goes on the roots not the leafs. Keep cuts flush with the stem no hanging bits of branches or leafs while pruning.
Keep it simple.
Dont do too much.
Leave the plants alone more (dont keep fuckin with them "cuz i readed this thing online some kid wrote about this trick he heard")
 
Thats exactly my mentality, Less i mess with it, less chance i have of destroying it :P

So to confer the leaves i should be taking off are literally the crispy run down ones and not the ones that are still in the process of dying (contain nutrients) ?
 
Hey Walter, In all honestly there's not many growers where i'm situated, and i dont know anybody personally to mentor me its why i decided to give forum a shot, so far very helpful! :D

By nutrient depleted i mean turned yellow. After youve gone through flower a few times youll know exactly what i mean. There is a predictable yellowing pattern. There will come a point that most of the leafs have been used up and should be removed, some strains dont have this happen much, but most do to some extent. Some strains youll have to spend a lot of time removing used up leafs every day if a large plant. In a outdoor grow you could spend an hour a day just on 2 plants during the time the plant is rapidly using stored nutrients. Keeping good levels/high levels of nitrogen going into flower helps this he less of a issue. Ive noticed some soils lead to very differant results as well. Try to do a few runs a few differant ways and see what goes best for you. I think soil is easy and more reliable than hydro. Organic tends to be easier than chem. Chem is pretty easy too though and what im using now. 1 teaspoon dry chem per gallon 1 feed per week and zero issues, pretty flowers.

From what I can see on the Canna chart Canna Terra nutrients come in two bottles, one which is used in veg canna terra vega and canna terra flores which is used in flower. But they are one part nutrients, meaning they don't have an A and B bottle. So I'm wondering if you are using one of the other Canna products like canna coco or canna Aqua which both have parts A and B used in the same amounts each feed. So If your using a different line of nutrients I'm not sure how that will translate or how it will effect the plants. I would use the nutrients as per schedule for that line but follow the light feeding schedule. Its all in the chart on the webite I linked in the other post. As an example if it were canna coco nutes then 3.4ml per 1ltr of water of A and B, or if using terra nutes then 5.3ml per 1ltr of just terra flores and none of the terra vega at this stage. Shame Pics cant be uploaded because I would like to see the bottles.

As for the pk13/14 feeding schedule says just for the 5th week (1.5ml per 1ltr) but a lot of people start a bit early at low dose and run it for a few weeks, its hard to say what stage the plant is in without experience of the strain and counting weeks is not an accurate way to do it. So running the PK at low dose and upping it then tapering it off to none for the last 3 weeks seems to work well.

Regarding dead leaves, if they are destroyed then you can take them off as they wont be doing there job anyhow. Don't cut them, just pull down at the base of the stem and it will just click off.

The other thing worth saying is chose a line of nutrients and run with them, don't mix and match one bottle of this line to another bottle of another line. Each line is balanced to be used as a whole. Some companies do one part nutrients, some do 2 or 3 parts, So mixing lines you could be adding more of one thing and not enough of something else. Personally I use canna. All the parts are usefull but only A and B and required, that provides all the NPK and micros I need. I still run the others because they all have a benefit, PK13/14 boosts the PK when needed, rhizo helps promote roots and helps when stressed cannazym breaks down old roots ect. All these fancy brands are the same thing mixed in different ratios. Some more fancy and overpriced than the others. They are just bottles of water with a balanced amount of everything the plant needs. Some companies just like to be more complicated than others so they can charge a premium. Mostly they are not worth the price.

A friend of mine has grown for over 20 years, hes used all the major brands in that time and these days he just uses tomato feed, kelp and molasses. He gets the same results

Anyway, enough of me waffling. Good luck. Look forward to some updates when this site gets its images sorted out.
 
Hey Corey, I am using Cana Coco A & B and Big Bud. Though I did order myself Jungle Juice Micro & Jungle Juice Bloom, They have been un-used.

Im going to tackle the leaves today and hopefully it will make it look better. Do i pull the ones that are in the process of dying aswell? (ie mostly yellow and dying but still has what appears to be a living stem to the plant?)

I ordered myself some PK13/14 yesterday and will start putting abit of this in my feed.

Ive not heard of Rhizo before but i'll start looking into it and hopefully pick some up from my local store soon.

Ideally what would be the best feeds for putting in Canna Terra & Clay Balls in a 25L Pot? I tried to figure the chart out but in all honestly it was like looking at something in a different language.

3.4 M/L of Canna Coco A&B & 4 M/L of Big Bud per L of water? And how much water a day roughly? ( I was using 1.5L but ive just upped it to 3L)

I've never attempted growing plants in my life (not even basic flowers) though i'm a fast learner so with a little help and guidance i should be on my way to producing some nice colas for myself and friends! :)

I think if I was to get a couple of likes I could post a link to PostImg showing my plants and their progress aswell as the leaves problem and after attempting to fix them, So if anybody reading this would like to see them, a quick like would help out alot.

Much appreciation
Ricky,

Ricky,
I would pull the leaves that are totally screwed and if the others get worse then pull them a week later as to keep stress down to a minimum.
Rhizotonic isn't needed, I like it though, its good for stress during transplanting and does help root growth. Its damn expensive though so I only use it as I transplant and if I have any major stress caused. It isn't a must have though like A and B.
3.4ml of A and B sounds reasonable with the big bud on top, Water with 3 litres and if nothing is coming out of the bottom of the pot then add another litre at a time until plenty a fair bit comes out of the bottom of the pot.
The best feed for Terra is the Canna terra range which is terra vega and terra flores, it wouldn't cost that much as the main nutrients in the canna range is reasonably price compared to products like advanced nutrients. I pay £31 for 5ltr of both parts (not each) It lasts a long time. That's for the coco, the Terra flores which is what you want during flower is £29 for 5ltr.

The Canna chart is pretty simple once you understand it, you will pick it up and I'm sure you will be growing without too much hassle I no time.

Best of luck! :bigjoint:
 
Did it today, i also decided to pull some of the dead leaves off my plant today and they came off so easily so think they needed to come off :P
Plants looking better, now ive upped to 3L its also now dribbling water and seems to be dampish soil instead of going dry a few hours into the light.
Thanks so much for the tips. I'll read up on the Canna chart aswell,

And with regards to the feeds, Im using Canna A & B (also cost me 31 quid for 5l of both :P )
And will make sure i look into replacing the big bud with something as efficient and cost effective!
