Would sm-90 help with this? I used to see it recommended for issues like this, but it has been a while.
It was originally made for spider mites, but I know it helps kill anaerobic nasties. I use it for PM if I get it, and also as a wetting agent. It helps soil take on water and I haven't seen any adverse effects from it with organic soil. Smells pleasant too. When I did hydro it was the go to for root issues, but that was a while ago.
Advanced nutrient voodoo, it's for root uptake, I used hydroguard 2 days later which is for root rot and root rot prevention, and a day later I used Advanced Nutrient Revive.. It basically starts production again Sent from my iPhone using Grasscity Forum
My method is above here are some more pics A big part of fixing it is stopping whatever conditions gave you root rot Sent from my iPhone using Grasscity Forum
