I aim for about 6.0 most times. I flushed it with 5.7 and got 6.5 run off on both flushes, used a gal each time. Keep flushing til run off is lowered?For coco..your ph is too high..aim for about 5.8...check the pH of your runoff..too high or too low will lock out nutes
Sweet sweet was on right track, ty for the info, happy growing. webuildsoldierz.comYes...bring it down.if you're flushing with 5.7 and its coming out 6.5..the ph is even higher...hence you're locking out nutrients-once you get the ph down..give it a bit of time and introduce a milder mix of nutes to begin with..and then watch your girl to see how she responds..Google online, their is a chart that tell you absorption of nutes at different pHs
cheers
