4x Northern Lights #5 x Haze

Walking on a thin line here.. Four days ago I checked the roots and they still seemed going in the wrong direction. Fed them hydrogen peroxide from the top of the roots so that the most contaminated parts would be the most exposed to the peroxide. Then I checked yesterday, and it still didn't look too good. I fired up the solution to get rid of this situation asap.. I put about 150ml of 12% hydrogen peroxide to 10 litres of water and watered them evenly. Got a burn scratch from the peroxide in my forehead, looked like a soldier for a moment and thought this is what the plants are going trough also.. The plants still look great on the surface. They ingest a lot of nutrients. Top left plant has a million branches, I counted. During this root rot thing I didn't realize how leafy the plants had gotten so I did a big defoliation operation. I also had read from many places that with LEDs you wouldn't need to manifold so much because the light from them penetrate the plants more.. I sure did fell for that hype.. The branches under the top ones are so bright green, but not for long.. I think they have a good chance to grow old and I'm doing my best trying to eliminate every possibility for the rot to take over.. Stressful sure, but I have a feeling we will pull this off.
