Ive been telling him hes over watering and the soil hes using holds water like a sponge ill tell him to dry them out.
Now last year i had gray mold on a stem and I washed the spot with rubbing alcohol and burnt that spot on the stem with a torch and never saw it again any chance this could work for him or do you think it might be root rot ive got some h2o2 he could drench the soil with and then set him up with some mykos tea and try to build up microbes again?
I'd suggest stopping the sterilization techniques. Instead treat w mykos and bb. Water it in to the root zone n let the pots dry well between waterings. Works very fast and will reverse the damages. Tried bleach, alchol, physan, peroxide, pythoff, etc did nothing. .. switched to coco and organic methods w mykos n bb, cleared right up. Had I done this first would of saved a 15 light grow. Lesson learned. Pretty sure mykos and bb are the only thing that cures n prevents crown rot .hope this helps somebody.
