Hi, so my clones are on day 15 since I got them (got them fully rooted). I think I may have over watered early on but they have recovered since then. Im using 3 part GH + superthrive.
The plants seem to look good in terms of new growth, but some of the older leaves are looking terrible. What could this be (pics attached)
not all the plants have these kind of leaves, but a few do, and its usually the bottom or older ones.
I was guessing mag deficiency on some of them, but the dark purple on some of the leaves has me stumped.

20 inches at 1000 watts is too close. move the light up some. try to get 85F temp down below 80 if possible.

Superthrive is dosed by the drop, isn't it? Try less (or none). It's good in tiny amounts when the plant has been stressed or transplanted.

Yes, by the drop. Label says it's vitamins and hormones. Smells like vitamins. Not sure of the benefits.
