How often and how much are you watering and are you clearing away any run off?

Love seeing girls under the natural sun matey and the darker one is looking very happy

Looks to me like N deficiency tbh. Nice to see a greenhouse grow :)

Yeah, it sounds like the yellowing ones just arent drinking as much so the roots are staying too wet which is not letting them drink properly. Staying sodden wet really isnt good for the roots

Go with raising them. And tbh the feed level is pretty high. I'd normally not go past 1ml per litre each A+B per litre unless the plants were really hungry but I think this is damp roots not hungry plants tbh

Have you upped the a and b recently? I agree with gmo but that's a hell of a lot of a and b per litre.
It's nice to be nice :Stoned:

It's probably locked the nutrient uptake now. You might need to flush first then feed 1 ml per L of each A&B. What ph range do you keep?

It certainly looks like underfeeding to me at first glance, simple enough to correct, just give them AnB 2.5 and upto 3ml a liter and daily feeds to plenty of run off should do trick. Aim at ph between 5.5 and 6.2 with 5.8 the sweet spot, they are big plants and will be and look hungry mate. :)

A flush through of your pots may also help them out before starting new feed regime only cus the coco maybe locking out ferts if it`s overloaded with too much food, basically it will cause lockout of some sort, run x2 or 3 water to pot size through your pots and fire back up feeding as above, they`ll be bang in in no time

Another tip would be to lift them pots of the floor allowing them to drain a lot easier.
