My main concern would be your watering schedule...
In my experience with rockwool, 6x a day is too much, I would say you would be better off perhaps 3x a day...possibly even 2x. Rockwool holds a lot of moisture for a long time.

If you're having success, great! but I would consider feeding less times.

(5.5 PH and at 190 PPM) that included "Great White:, Big bloom, and grow big. Its a pretty weak mix but I have seen no signs of over fertalization. I made a drip irrigation system with a cheap water pump and five gallon Rating: 5
