Pennellostarted grow question 4 years ago HI guys, im literally going crazy! Been flushing them for an overfert, ppm were extremely high..Now at the 3rd wash with only water ph 6,2/5 and ppm at 400, i get a runoff with a ph of 7,4 and a ppm of 1500.. Any suggestion? Should I just keep watering at lower ph like 5,5?
