H202 is unstable and doesnt last long... others use pool shock

I don't know what advanced nutrients you were using, but they got you brown slime both times If i gather this correctly. Now you switched back to technaflora which has proven itself to you for 4 grows. Did things improve? What exactly are you using now with technaflroa? What did you use from AN. Anything organic? anything with sugar? Any microbes?

Too high of a nutrient strength will damage the roots, leading to rot. Are your airstones now clogged, dropping your DO levels? I try to change airstones every grow.
