Well....Im loving them but still cant get this ph to sit right. I tested it yesterday in each pot, the control, and the rez. All of them rose to 7.2 from 5.8. I let them drink all the way down then mixed up the nutes in the rez, then let it autofeed. The plants look great in my eyes. Leaves all look perfectly green...only some red stems here and there but mostly green. Any idea on the ph fluctuations?
