Looking for some advice on low EC run off, this is the third day in a row, using coco medium, day one ec in at 1.4 as it has been for a while, around 15-20 % run off come out 1.2, so the next feed I upped the ec to 1.6 in and come out at 1.4 again 15-20% run off, and today 1.6 in and 1.2 out, always 5.8 ph, I’ve just flicked to flower and defoliate quite a bit, it’s amnesia haze if that makes a difference, am at a bit of a loss here, feed is always evenly distributed by hand ,head scratch
