Could use some help to pin this problem down

when you get it go ahead and give them a foliar spray if theyre not showing large flowers yet

spray them the same amount I recommended

your brand
0.4 mls per gallon

south AG
1ml per ten gallon

id spray them 2x three days apart and watch them green up almost over night the centers of the new growth will turn dark green

your plants are going to love it

I love to get the iron up just a little higher than what most brands provide, it really ads to the green and shine of the leaf

Dropped everything and got some. Just finished giving them both a spray of the solution. I'll start adding it into the feed from the next watering as well. Thanks for the advice. I clearly still have novice eyes when it comes to spotting issues but as i'm seeing examples with my own eyes it's becoming clearer.

Looking forward to seeing the new shades of green when these ladies start lifting some iron :lol:

Week 3 + 3 days.
By far the healthiest I've ever seen these girls. Even the smell is strong already and normally I don't have to worry about my carbon filter being on 24/7 until week 5 but i've had to shift it to full time already.

The iron ended up taking about 2 weeks to really show. I sprayed twice in the first week and have continued to include the iron in the water feed since. I check the plants visually top to bottom every couple of days and (knock wood) all appears to be looking good.

I edited my last post

it was suppose to say "don't over do it"

although having said that..its hard to over do iron but still no reason to try

Yeah to be honest I didnt really think or know there was an iron issue but even the small amount that you said to add has slowly over a couple of weeks given the plants a nice green to the leafs. These photos are after 2 feeds of the bloom mix too so less N and more PK. It almost feels like I'm on auto pilot now. Feeding schedule and the like have found a nice rhythm.

I also added another LED light to the mix. If any issues come up now I'll have to consider that may be the issue now and not what i'm feeding. I'm checking the tops of the plants multiple times a day for light burn. I'm thinking if nothing shows for a couple of weeks its safe to assume they are far enough away.

I wouldn't call what you had a major iron issue

most people get that yellowing and ignore it and all is good

but your mix was a little lighter than most on iron so its worth the trouble in your case

im going to start foliar feeding my plants every 2 to 3 weeks or so with peters micro mix s.t.e.m.

0.1 grams per gallon

I did it a couple times and the plants absolutely love it

I'm sure I had the yellowing in my last grow as well but I'm all for each grow finishing better than the last. When I first started it was from a 250 hps guide with dreams of getting 7 oz per grow. Best I've done so far is 4.9oz from 2 plants which was my last grow. With the right feed from day 1 and a good 4 weeks of veg I really hope third time is a winner.

See the foliar stuff seems to add a new level of work that I don't want to touch until I get the normal steps down first. It's taken me 11 months to learn that when it comes to plants you have to give them time to respond one way or another. In my first grow I remember changing my plan multiple times a week. By the time signs were showing I had no idea what actually made the improvement.

Have you ever re-potted a plant in week3/4 of flower? I'm having to water ever 1.5 days. The bags i used last time were fine but these girls are at least a third bigger and love to drink. I dont mind watering daily if need be but if a re-pot now wont stress them i'm half considering doing it this weekend.

no
ive not done it that late

how many watts are you pushing now and watt type of bulbs?

what size pots?
Currently in PB18 bags (10 Liters(2.64gal))

Wattage is 400(at the wall reading via meter) via two LED lights. One is cree full spectrum so contains more green/yellow than it needs and the other is a custom cob LED setup so full spectrum is covered but the majority of light comes via red and blue. I got the cree one first but two weeks ago I knew it was only really going to be enough for one plant not two so I ordered a different one so I could cover my bases and see for myself what the difference is. They are a perfect example of how much the LED market is confused about everything it puts on the box. Both of mine draw 200 watts from the wall but one is boxed as a 300w light which should only draw 130w and the other claims it's a 1200w LED that draws 170w. So I guess its comparable to a 400HPS at a minimum maybe a 600w. It's all in a 2.6x2.6ft tent.

Yeah I probably won't re-pot. i'll move up to pb28's next time.

So I've noticed a different trend in my grow this time around too. Last grow my run off ph always went down. If I put in 6 it'd come out 5.5. I run off about 15-20%. When it went down to 5.5 I took this as a sign salts were being flushed out. But this time around the ph is always up. when it goes in at 5.9 it comes out at around 6.4. Not sure if it's relevant but PPM is around 700ppm IN and 1200ppm OUT.

Plants still look great but this just doesnt match my history so I feel the need to find an answer. I've tried searching but all i end up with is an infinite amount of people saying different things.

Actually I've read enough now that it seems this is very normal for coco. to go in at 5.9 and come out at 6.2-6.4. I guess I'm just now seeing what normal run off is compared to my previous grows :)

Interesting issue starting up here.

It's currently 2 days into week 5. I've been feeding bloom food for the last 2 weeks.

The area of the plant shown in the photos is also the highest bud under my new LED. I've already raised the lights about 5-6 days ago as I found out my LUX meter isn't giving a true reading for my new LED as its very heavy on the red. Only other thing I can think of looking at my problem chart is Sulfur def as I did notice long purple streaks on one part of the plant. They have been nice and green for weeks. I'll pull the plant out and see if I can get a photo of the purple streaks. It's actually different from the purple colouring that use to be on the plant. I also read people see plants have a little issue when changing from veg to bloom. I'm not sure on this as I don't recall ever seeing it before.

I'm thinking it must be the light causing the yellowing. I can't really see the issue coming up on places elsewhere. Not yet anyway and the other plant which is a different type looks perfect all over and it's shorter so it's never been as close to the new LED.

Photos of the purple streaks attached. Not sure what they mean but they do seem new.

I'm wondering if I'm mixing my food up in the wrong order too.

This is the current order that I put it into the water. but from what I've been reading today I should be adding the Epsom before I add the BLOOM. The Budstorm says on the bottle to water down before adding into nutrient mix so I assume this one going last is fine. So that just leaves Epsom and Iron that I'm not sure when they should be added if different from the list order below.

Flairform CMX
Flair BLOOM
Epsom Salts*
Yates Iron Chelate*
(Budstorm I add into around 700ml of plain water before adding it into the 20L container.)
BudStorm

I should have listened more in chemistry class :)

I've learned a lot over the past year. I put all the information together and started eliminating things I knew were not the cause. My last batch of food I lowered the BudStorm because it looked like I had a Cal/Mag issue and I put that down to the BudStorm possibly being a little too much maybe. I figured half the budstorm is better than none and if it's causing the problem I should see it turn around.

In the mean time my aliexpress order arrived of new ph pen calibration sachets. I HAD been manually using my dripper ph test kit along side my pen every month to confirm they were both in the same range but I got lazy and started just using the pen. Any way as you can probably guess I calibrate my pen and the damn things been out by about 0.6-0.8ph downwards. That's right I've been feeding ph 5-5.3 food for at least 3 weeks now.

I have two different strains growing. The indica has been the only one that has showed signs. The sativa still looks perfect. I managed to find only one blemish but the indica has gone down hill in the last week. I gave it a flush with new food and ph of 5.75 lots of run off too.

Just need to wait and see now. Most of the indica still looks healthy and the sativa well it's clearly a hardy strain so shouldn't suffer too much but I guess it depends on if my current assumption is correct. Low ph seems to tick the boxes and is an issue that needed to be fixed either way.
