Hi all
First grow with rockwoll. Feeding twice a day by hand, was getting cupping and yellowing leaves, backed off on the watering and did my watering by weight of each 6" cube. My PPM is 750-800, temp 80-88 w cos, 6 1000, ph 5.9. I back off on the watering and did it by weight if they were light I watered. I have noticed new root development and less alge on the tops, but I have htis issue now
