Bruce banner #3. I’m in coco feeding 3x per light cycle. Coco doesn’t get too dry or wet although there was a 1 day the tank ran dry maybe a week ago missed a couple waterings before I got there. 2.0ec and 6.3ph with ambrosia cropz fert. These have 1kw DE lights on one side of tray and 750DE on other side. Any thoughts? Could be from the dry could be nutes or lights too strong?
