Your not bleaching anything at 18" with a 600w.

Especially with proper air flow.

1. Drain your buckets, fill with Plain water. If the EC creeps up at all in 2 hours you have salt build up in your roots. Let it soak for a few more hours and then give fresh nutes.

2. Whats your PH? 5.6-5.8 ph with all veg nutes first 2 weeks of flower. If your running your bloom nutes already, your probably needing a little Nitrogen and maybe calcium*

3. How long it been since you replaced your bulbs?



*you can test by foliar feeding at 30%. Add only N. If it fixes the problem your good, if not try some cal mag. Has N and calcium. Start with half strength.

Theyre on the first page, the only other thing i can think it may be is an immediate change of nutrients when flower started with low nitrogen levels when theyre needed for stretch.
Funny u say this, I was reading about this somewhere else just now... Yeah my veg and flower nutes are obvs different. Is this a problem???? Will it fix itself??

Its either problem 1 or/and 2...

Could be problem 1, not problem 3, bulb is brand new.... I will start will problem 2 and foliar feed although my ph is 5.7-5.9 range. I have general hydroponics Armor Si 0-0-4 or GH Floralicious Plus 2-0.8-.02 which one should I foliar feed with ???? Also I use GH technaflora series and right when I go to 12/12 I go to bloom nutes.

Some nutrient charts say to run the veg nutes two weeks into flower. Ive noticed in my coco and soiless grows that when i switch to bloom food right at switch that the leaves yellow more quickly. But its more patchy all over the plant as opposed to just new growth at the top. Ive been tinkering with it for a while and im currently testing six weeks of veg nutes and the last two of flower, well maybe five and three, who knows yet, but i ran veg nutes through to the end a bunch of grows back and they loved it. They stayed green until almost the end and the production was huge. I think in part because there was so many leaves to feed the plants circulatory system left until the end. Anyway to answer you, no it wont fix itself. Yellow doesnt turn back to green. And yes, any yellowing this early is a problem. I sont think its too bad though. You have a couple things to try that arent going to hurt anything so no worries man.

Why do you want to foliar feed when your plant may have leaf issues?

Never had a plant like this, I almost think it has stopped growing but its hard to tell do to scrogging.... Now on day 12 of flower when does the flowering "stretch" occur the most... Also foliar feed with the GH florioulious plus. Gonna change the nutes tonight and see whats up.

Not even sure plant is growing from whatever is going on. Could a deficiency stop growth??? Plant is drinking probably .75 gallons a day, ph has been 5;7-5.9, and ph has been steady in the 875 range.

OK flush is about 3 hours into flush... water out of tap is about 145ppm then I added florakleen and ph'd down (not sure I needed to ph down) ppm then was about 175... 3 hours later ppm is about 210, so ppm went up about 35-40 points.

My fucking message is above starting with ok flush is about 3 hours into flush... Basically my ppm went up about 35-40 pts in 3 hours during flush. B

Does a ppm that goes up 35-40 pts mean there was salt build up???????? PPm during flush went from 175-210.

Feed fresh nutes. Keep ph @ 5.6-5.8. Raise light 24" above canopy.

Sounds like you have a sensitive girl.

You have circulation on your canopy right?

I think he was listening to me :)

Foliar feeding is a great option to treat certain defeciencies quickly during a stressed period. However you better be damn sure you know eexactly what the plant wants/needs or you can run into problems.

Wasn't suggesting for this issue, only saying it can be done. Its a great way to jumpstart a soil plant in a couple days rather than 4-5

So now ur saying it could be just leaf bleaching??? I don't know, the plant like stopped growing the last week or so... The plant has like 20 total calyxes on it for the last couple days... It stopped growing and developing, but ph was always good and the plant was drinking like .75 gallons of water a day.

DO YOU HAVE A FAN CIRCULATION YOUR CANOPY UNDER THE LIGHT?

If I remember correct you said you switched from veg to bloom nutes?

Your girl might be wanting veg nutes still. She sounds like shes a little picky! :)

It can also take a plant a few days to get use to a new fert mix if you make big changes

Keep your levels right. While you wait

Nitrogen promotes veg growth

If you suddenly stopped delivering this to the plant and the plant has mostly PK available, growth will slow and defeciencies occur. The plant doesnt need PK in heavy levels until week 3+ in flower.


Raise your light to 24" because your plants are obviously looking shitty. Give it 50/50 veg/bloom for a couoke weeks if your in such a rush to start bloom fert. Once you see h did forming switch to the bloom.

Raising the light will create a less harsh environment while you get this under control.
