Nutrient/soil recomendations for autoflowers

Just wanted to say hello everybody, in doing my research, I kept getting links to forums on this site, so i thought it would be a valuable resource to join.

Anyway back to the core matters/specs heres my setup:
-blue mystics auto flowering (from nirvana shop)
-250w hps lighting
-1 gal pots (im only growing 2 plants at a time (atleast for now))
-growing in a good size walk in closet.
- box fan
So here is my questions:
I originally wanted to do hydroponics, but i didn't want to do too many new things at once.
That being said I would like to try using hydroponic nutes in a soil grow. (I want to have fun and experiment as well) Ive purchased 1 qt of ff big bloom, and 1q of ff tiger bloom. (ive read they work well together)
So this leads to my first question/concern. Ive read you don't need to give an autoflowers veg nutes. (because the veg stage is so short)
1. Would you guys agree with that statement?
2. My other concern how much nutes to use/ and how often? I'm completely new to the concept of nutes, but ive read a handful articles/forums, but it hard to find an article that pertains to hydro nutes, soil, and autoflowers lol. I've read one should use 50% nutes of what you would normally use.(in a hydro). Can I just water with small amount of nutes in the water everytime?
3. Is a one gal pot big enough for an autoflower?

4.Another topic i read is EC of your water. Is this a serious variable I should be concerned with (atleast for someone with my experience)I'm not looking to win the cannabis cup or anything, but just make a bud better then all (using "all" loosely) the "brick buds". In terms of water, would it been fine as to just use tap water that sat out a couple days? (to get rid of chlorine of course)

Again just wanting to save money on bud and educate myself. Strictly for personal consumption/close friends

Thanks for you help in advance guys!

PS I understand the core basics of growing (growing stages, lighting etc..) so don't be affraid to be specific.

I'm new to growing so i can't answer some of you questions but i can get you the nute guide ive been using and i haven't had a problem yet. I got this from a member of the AFN website.


Week
1 pH water only

1.5 add in Big Bloom to the mix at 1/2 tea spoon

2 1/2tsp Grow Big 1/2 tsp Big Bloom

2.5 3/4 tsp of grow big

3 1tsp grow big and 1/2 Tiger bloom 1/2 tea spoon Big Bloom

3.5 1/2 tsp Grow Big 1/2tsp Tiger bloom

4 1tsp Tiger bloom 1/2 tsp Grow Big

4.5 Clean pH'ed water to clear out salt build up

5 2tsp tiger bloom 1/2 grow big

5.5 1 Teaspoon Grow Big

6 Begin Flush for the final weeks. At this point i can flush for a week before i begin to see yellowing of the fans.

Thanks for the quick reply trojantouch!
Was these nutes meant for hydroponic or a soil grow? (I'm doing soil). I guess I'm asking because I'm shocked at the bi-polar amounts of nutes from week to week. And I'm surprised that you use the "grow big" throughout the grow. I just figured the grow was only used during the veg stage (if used at all in autoflowres). (roughly the first 10-14 days).

I would suggest using Biobizz Grow and Biobizz Bloom, and possibly Biobizz Fish Mix. Biobizz is an organic range, theyre great and it is very hard to overfeed (nutrient burn) your plants with them.

Having grown autos quite a few times i would suggest not feeding them for the first week, just PH'd water.

Week 2 - Feed them 2ml of Grow. ( ml = ml per Litre)

Week 3 - 4ml of grow

Week 4 - 4ml grow, 2ml bloom

Week 5 - 4ml grow, 4ml bloom

Week 6 - Carry on feeding them 4ml of each until 2 weeks before harvest, then you can cut down to 2ml for the final 2 weeks, maybe even feed just PH'd water on the final feeding.

If you were to use Biobizz Fish Mix as well then use half Grow and half Fish mix (So on a 4ml Grow feeding you would use 2ml Grow and 2ml Fish mix).

Ive always had great success with this schedule, you don't have to stick with it 100% but its a good guide. You will find that soon you get to know how much you can feed your plant, if it could handle more nutes or if you should cut back and feed less nutes.

I would also advice getting a Cal Mag supplement and feeding it to your plants at around weeks 3, 5 and 7. This just ensures that you won't get any deficiencies towards the end of flower.

I can guarantee if you stick to this you will not get nutrient deficiencies and you will not burn your plants, just be sure to get the PH to around 6.5.

You need to go look for more information on it.

Thank you kush2180!!
I really appreciate your input. I will def have to give those nutes a try next time around. (I already bought the fox farm) now when you say to keep my ph at 6.5, do you mean the water or the soil itself, also how do you test yours/ how often? Also how critical is the cal mag supplement? I'm trying to keep costs lower but if it makes a big difference I'm down for it.
Another little Q: I have only the tiger bloom and the big bloom, do you think i would see much better results if i additionally bought the grow from ff as well. or do you think i could get by with what I have?

You should adjust the PH of your water to 6.5.

If you have bought quality soil such as Biobizz Light Mix then the PH is already at 6.2, which is fine. Otherwise check the bag of your soil for the PH, if it doesn't say then you should really buy a soil PH kit to find out and then adjust the PH to suit.

You should always PH the water you feed your plant. Some people test the initial run off when they water their plants, however if using quality soil this isn't necessary. I test the PH of my water with a PH dropper kit, they cost $4 and are very easy to use and accurate.

Cal Mag is only 'critical' if your plant develops a calcium or magnesium deficiency. As this is your first grow you won't know if they will because you haven't grown the strain your growing using the soil and nutrients you have. Its very handy to have because if you do develop a deficiency you can fix it straight away and not potentially ruin your grow due to trying to keep costs down.

I have no experience using tiger bloom and big bloom but I would suggest buying the grow nutrients as this will help against deficiencies and potentially increase yield.

For the sake of $20 for the Cal Mag and Grow nutrients I would 100% buy them. What is the point getting this far and potentially fucking up because you wanted to save $20.

Hope this helps

edit: You should really read more... All this information is easily found on this very helpful forum.

Thanks so much for your info kush2180!! I will def have to get some cal mag (it does seem silly to ruin a grow to save 20 bucks haha)
As for the grow nutes... I will def purchase them aswell! As for the soil, I would think home depot has something decent.

When everything gets going ill be sure to post pics! (prolly 2 weeks)
Thanks again Kush2180, you've been mucho helpful!!

Happy to help buddy, keep us posted.

hi, im not trying to be a dick or troll your post but i have a question about those nutrients, im gonna grow for the 1st time some dinafem white widow auto using biobizz products, but i have a question about the nutrient schedule, since im too noob for this i have to ask, lets say im on week 3 and obviously i need 4ml of grow ( according to this schedule )...now lets say i water my plants 3 times a week, does that mean i have to use 4ml of grow every time i water my plants during week 3 ( meaning 3 times ) ? or do i need to follow that schedule on a 1 per week basis no matter how many times i water my plants? and finally what pot sizes do i need to use this nutrient schedule
? according to what i've been reading 5 gallons is the perfect size am i right ? thanks for your help

For soil use something like Fox Farm Ocean Forest and for nutrients I would use Sensi Bloom for both veg and bloom. For supplements I would use Fox Farm Big Bloom and Great White Mycorrhizae

Obviously the bigger the pot the better (to a degree). From my experience I would advise using 3 gallon pots as any bigger and its pointless due to the short veg period. It also costs more for soil and nutrients.

Always use quality soil such as Biobizz Light Mix. Using crappy soil can cause a whole load of problems such as nutrient burns and PH issues (Twisted leaves).

I generally water my plants every 5-7 days and feed them at every watering. If I was to use a 3 gallon pot I would feed my plant with 3 litres of water or until I got 10-15% run off.

You shouldn't be watering your plants 3 times a week.

How do you determine when your plants need to be watered? I normally stick my finger into the soil bout an inch deep, if I can feel its damp at my finger tip then I know I can leave it another day and check again. I also lift the pot and feel the weight. Check them before you water and after you water, and remember the difference in weight. Soon you will know if it needs a water purely by lifting it.

Hope this helps.

Just wanted to post a pre grow update, just got the light today 250w HPS, for now I'm just going to use HPS threw the whole grow. Anyway here some pics.

Lastly I went to Home depot looking for a soil. I could not find any soil that did not contain pre mixed ferts so I didnt buy anything. So in googling things I found out theres a local hydropontics shop, (I just moved here about 2 months ago). Went there and asked for a soil that was fert free and this was what they recommended me ( I did specifically look for biobizz biz light mix but they didn't have it)

If you cant read the bag its made by Sungro, Sunshine natural and organic planting mix. Ingredients are: 75%-85% sphagnum peat moss, perlite, dolomite lime (for ph adjustment (PH of the mix is 5.0-7.0 oudda the bag according to the website)) and an organic wetting agent (yucca extract).
I'm pretty anxious to run ph water threw the soil (before i plant) and see what my end ph is.

All being said, questions/comments/concerns are always welcome.
Thanks for reading,

A PH of 5.0 - 7.0 is a massive range. You need to buy a PH soil test kit and find out the PH then adjust it accordingly using Dolomite Lime. Do not just start growing with the soil as it is or you could be locking out very important nutrients. You have been warned!

thanks again kush2180, just ordered a soil ph kit on ebay .

This is going to be my last update, then im going to move this thread to a proper spot. (I'll let you guys know when i make it)

The blue mystic seeds have arrived (cool shipping btw) i put 4 of them in a paper towel, sealed it in a sandwhich bag, and put it under our modem. 3 of the 4 seeds cracked and were planted yesterday (the 3rd day) the fourth seed which i just checked still hasnt popped (beginning 4th day of germ) I think ill give it another day or so, then im going to germ the 5th seed to replace it.
Heres a pic of the set up I guess all being said it about ehhh 75 degrees in there (I need to get a thermometer) The only thing I have a concern with at the moment is am I giving too much light to the little girls/should I even be exposing them to light right now? The 250 hps is about 3 feet from them. I def don't think its making the girls too hot because the top of the soil is still pretty moist after a day of the hps being on for 20/4. Not using any nutes, and theres no nutes in the soil eather. (oh btw i ran PH water threw the soil waited an hour and tested the PH of the soil...6.7
As always comments/questions/concerns are always welcome!

And the other black container is just where i pour the run off from the plants, i figured it would be good to add a little humidity in there.

Hey everyone, I moved my blue mystic grow to a new thread called:
[h=3]1st Grow,4 Auto Blue Mystics, Soil, FF nutes, 250 HPS, Walk In Closet[/h]under the Auto Flowering strain section.

Thanks again everyone for your input, tips, and knowledge.
