I was able to get things under control but i still do not know exactly what the problem was. Anyways to get things right i flushed with RO water for 2 days, while foliar feeding 250ml RO water and 2 ml of liquid iron sulfate i got from the pharmacy. I think i was getting an iron deficiency from overfeeding. I dont understand why but i can only feed at 1EC or the problem comes back, any ideas

Just found this post after being inactive for 7 years lol. Well I kinda laughed looking at my pics. This is classic case of overfertilization for anyone wondering. It’s so easy to look at the fertilizer bottles with their cool graphics and think “mmmm if I was a plant I would love this. Bud candy, grape carbs, molasses, sweetener yes more please.”.....haha. Well anyway I’m not claiming to be a pro but a good basic GH 3 part is all you need to grow awesome buds. Less is better!

OK i did a water only flush a few days ago and the plants did get better however the first second my PH goes above 6 the yellowing starts. I cant believe how little nutrients the plants use. If I start my PPM at 400 they are at 430 the next day! That still means i am over feeding correct? They must be so stressed they dont wanna eat. As far as the weird growth on the buds are you sure thats from the plants trying to reveg?
This is why your yellowing starts.

Iron becomes, so much more available below 6ph.

Calmag above ph6

Even though you're supplementing iron, in your calmag, there's way more calmag than iron. Calcium and magnesium, may well be locking out iron.

I don't think it's a case of underfeeding either. But overfeeding. I'm gonna say that's why it improves a little, with straight water.

IMHO. It's not the ppms that are the problem, as much as its your balance.

Iron is one of the hardest things to be deficient in. It's used, and absorbed so slowly.
With all the balanced fertilizer out there today, iron deficiency is a thing of the past.

It could be a lockout of sulphur too. Does the yellowing form between the vains?
Or all over, doesn't care?


Looks like you have a lockout to me.
