RQS AK AUTO x3 (FIRST EVER)

Week 7 started with interesting issues with plants, first lower leaves looked bad and I defoliated them, either it was due to too much water or light not getting to lower parts, because top of plants are very crowded and nice, bottom is kind of empty. Also once after watering I saw in plant no 1 watering tray small white worms, they appear due to lots of water standing still at bottom I guess, so i went 2 days dry, so it dries out, then watered again, now I've never seen them again, only this one time, I hope roots are okay. :( Defoliated a lot lower parts, by mistake took few useful stems (not that important ones, but still) :( Still adding bloom nutriens this week. Not sure when to stop and do a flush.
