Ok look, I am not an idiot. Well not much. I can read, I can figure my way out of a paper bag and I can tell you I have read on this site over and over people saying that the ppm in flower should be 1500 to 2000 to 3000. I have seen people say to start at 2000 ppm. I have been in flower twice with very large plants more that 3 weeks in and every single time I go over 1100 ppm I get burn on some if not all. I keep my PH at 5.5 to 6.5 and never change it more than 1.0 in a 24 hour period. So if you can explain to me why this is then please do. I am in hydro tubes with an areo set up with two 4 inch air stones in each rez, air temps in the upper 70's, 1000 hps on mover, rez temps cool to the touch. So what do you experts have to say about PPMs that can help???
