I stopped growing a couple years ago due to those fuckers, brought in some clones and they infected 3 4x4 beds :( They are a bitch and extremely hard to get rid of but its definitely possible, from what I've heard met52/
botanigard 22wp works(I have some on hand for emergency situations haha). You could also try tweet mint in high doses, that's probably what I would start with tbh because its cheaper. It will harm beneficials but it is completely safe, its just peppermint oil and natural enzymes which prevent bugs from molting. Foliar every 2 days and root drench making sure you get every spot of soil.
I wouldn't go near that promis shit haha
Good luck brotha, honestly if the genetics aren't that amazing I would probably just scrap the current soil clean everything and start a new with seeds or if you get clones quarantine for at least 2 weeks imo
