These are in straight coco 2gal pots and this issue has plagued me most of the grow, mostly after switching to 12/12.
Feeding GH nutrients with tap water. 2.5mL calmag, 4mL micro, 6mL bloom
PPMs are around 600 at 6.2 pH
60% RH, 80 F

What is your tap's ppm before adding anything?
6.2 is a little high personally, I shoot for 5.7.
I'm seeing a lack of nitrogen, unless you have a really light strain.

I agree one of them is really light. My tap ppm is around 180

That is some really light feeding. If your tap is 180 and you're feeding them at 600ppm that's only giving them 420ppm of available nutrients, um, that's what I feed my seedlings. This girl gets 900ppm daily. She is mid week 6 here.

Gotta remember coco has almost 0 nutrition. If you don't give it to her she won't get it.
