Well I have 2 separate systems going. One in ebb & Gro the other in Deep water Innovations( 2 plants in the same juice). The ebb and Gro seems to be on track now had nutes to high changed resivour. ppm is good now. The 2 in the DWC is where one is real dark green the other is much lighter but healthy looking. The darker is Crystal the lighter green is white widow. The darker is budding up real nicely the other is slow to flower very strange .
