GMSgrowsanswered grow question 3 years ago Lower your ppm down to 300 ppm 0.6 ec and your ph is at the high end for veg, so water/feed at 5.5 for a couple days and then steady at 5.8 and check your runoff ppm once in a while. Around 600 ppm 1.2 ec for autos can be all they want in veg. You need to read your plants. You work your way up to those levels though. Cheers
