Yeah I have three out of ten plants that are pretty fried. I have another month before flower starts so we will see who pulls through. I may have to pull a couple if they herm. I have one super healthy Bodie plant that was right next to the most affected plant and it is fine. All the plants got somewhat burnt due to sulfur being on the plants and me not getting enough off before I did an oil spray. Man the sulfur didn't even tough those bugs. But the oil/soap spray sure did. I am not going to say they are dead and jinx myself haha. But I haven't seen any sign of them and have been treating heavily with the home made spray and Green Cleaner. I think next season I am going to remove all the dirt from the greenhouse and start fresh, and maybe bill Trustfall for all the expenses....
To the OP, I highly suggest the home made spray with soap/alchohol/H202. I don't have the recipe link handy but I can find it for you if you want. But you can only spray during veg. The Green Cleaner is expensive but it seems to be keeping them off since I did the oil spray. Spray, spray, spray and keep spraying. Kill them all before these things spread everywhere and we are all f'd. Probably some government bug meant to kill cannabis lol. Hemp Russet Mites only affect Cannabis and thats it...pretty strange.
