Hey everyone. I seem to have very bushy plants and am getting some brown tips on most leaves. I was feeding around 700 ppm but since I had high ppms in runoff I've backed off on the nutes a couple weeks ago and been feeding between 200ppm and 500ppm. I am using RO water and was using 5.8-6.0 ph but my runoff was 5.3ph and high ppms and the brown spots were starting. So lately I've been going 6.1-6.4ph and the runoff has been the same. Also I'm getting 100-200ppm. The plants seem stunted lately however. Today I moved my LED lights further away hoping it was associated with that. Nearly 3 feet away from the tops. I'm lost.
