Fast Buds FF9

Day 71 Day 22 12/12 Day 8 Flower - switching over to a drip to waste system. I can still hand flush every few days or as the plants tell me with out having a full res change. Performed a little defoil to open up the budding sites to light. Day 73 pH 6.0 ec 1.49 temp 66F will change res completely tomorrow. Plants drank and ate hard past few days. Seems to have responded very well to the last defoil. Day 74 res change reset to pH 5.9 ec 1.85 temp 66F. Cleaned flood tray and drain lines with H2O2. Mild algae growth on the table no more. As soon as vertical growth stops, will switch to bloom nutes formula. Current final NPK ratio of reservoir solution is 2.16 - 1.58 - 1.65 Day 75 pH 6.5 ec 1.65 temp 66F. pH down (10ml) to 5.9. Plants seem to be feeding well, going to add more nutes tomorrow with a little res top off. Day 76 pH 6.1 ec 1.64 temp 65F Day 77 pH 6.2 ec 1.64 temp 66F
