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.
