EventHorizan gave you great advise a month ago. I'm sorry you didn't heed it.
To it, I would add:
stop thinking that dropping your water temp is going to eliminate your root problems, it won't.
stop switching from live to sterile and back again.
stop using products. rdwc only works if you keep it simple.
I would suggest that you stick to soil. it is more forgiving for your skill set.
pay attention and LOOK at your plants. that's the first step in learning how to read them.
fuck, if you spent half the time looking at your plants as you do posting you wouldn't be so embarrassed for having such an infestation.
and being a dick in PM's will get you banned.
