just started taking tds readings, today was my feeding day, week 8 of fox farm trio, amended water was 896 ppm and a ph of 6.5, tested the runoff, ph of 5.75 and a ppm of 1300( taking average of both plants). I've been noticing yellowing of leaves randomly throughout the plants, having already made lighting adjustments, figured I must be in a bit of lockout, seeing the ppm numbers for the first time. waited about 20 min, flushed ea w 1 gallon of spring water(ppm 0008/ ph 6.90) waited 15 more minutes, and flushed again w fresh water( same ppm/ph)

set up scrog netting
lowered lights, and decreased power to 550 umol
partially broke a branch a few days ago, taped it up firm back to the other brach, seems to be fine
