hello, I am wondering in general what factors make leaves droop. I believe I had excessive dirt/algae buildup in my system. I believe it is damaging my roots somewhat and causing them to slow growth and droop. I noticed a slight brownish tone to my roots as compared to a normal pure white. Sorry I dont have pics, but is this possibly my problem? I use peroxide, and have mantained perfect levels of nutes and ph so dont know how this happened.
