No rockwool experience. But I know PH is important for that or coco.ebb and flow. rockwool. im having some leaf chlorosis and purple stems. i know its a magnesium problem. i just dont know if im locking it out by feeding jacks full strength 3.6/2.4/1.2 or if i need to bump up the ec from 2.4 (jacks 2.0 +.4 tap water ec) to maybe under ~3ec
Imo, the jacks 321 is better with half the epsom. I use RO.
I also bump up the cal mag for my coco.
