Mid-week I noticed that the plants were hungry. Lowers on both yellowing, and I realized that while I started with an initial 1g Maxi at planting it wasn't enough and I was slightly off my usual schedule by a week. So on Wednesday I fed with 2g Maxi (1g gro, 1g bloom) and I'll bump it up to 3 next feeding.
One of the plant obviously has mutant tendencies and whorled leaves, we'll see if that ends up being full whorled phyllotaxy or not. The varigation seems to be stopping.
Lights were adjusted to 41DLI, at ~730ppfd.
