Also, Since I saw this problem I have not changed nutes on this system or added any nutes. Just fresh water to keep up the res level. My ppms are in the 400s and it seems all is fine. A guy sproutco said it was caused because I used the lucas formula with gh nutes. So I just bought some flora nova to try now. I try to keep things as simple as possible for myself you know. And I dont know enough to start playing with nutes. I am getting old you know.
How often should I flood the cocomat rockwool setup?
