Imo if you drop your humidity down and have good air flow in your room, you should be able to eliminate the problem in the long run. For sprays I use powdered sulfer, all it does is change the ph of the leaves so PM can't grow on them. Works wonders but you can't use it in flower because it will burn the hairs. I keep my RH at around 40, plants love it and no PM. Some strains are more sensitive to PM than others
