These were transplanted 5 days ago, didn't really have issues till I saw some mites a couple days ago, and hit them with azamax. I also fed them on that same day using Advanced nutrients half strength mild feeding. My ph meter had broken earlier so I had to use the ph test kit, so there's a good chance I screwed up the ph as well :/. It looks like too much nitrogen/overwatering and possibly ph off? Any help is appreciated, I don't want to make problems worse by chasing issues that aren't there. I also checked the bottom of the roots for pythium, heres what they looked like. They are all in 2 gallon pots with 30% hydrocorn/70% coco, the pebbles are on the bottom of the pots. They were watered with 800 ppm nutes. Air temps are around 80, sealed room at 55% humidity. Water temps are around 70.
