Well kinda not really, I had PM issues starting on a few leaves 3rd week of August 2019 (outdoors) and was able to hold it back from getting bad enough to spread to the buds. Selective defoliation and greencure foliar sprays helped for me. I also gave the most affected plants h202 wash which worked pretty damn well to remove the PM.
I dont have much experience with indoor if thats what you got going on, but good airflow and keeping your temps/humidity in check is a pretty universal thing when it comes to preventing PM.
Along with cutting off leaves (reasonably) and destroying them, theres tons of different foliar applications that can assist, just search "PM foliar spray" on google. Picking high resistance strains, preventative foliar sprays, and planning ahead are great tools for next time. If you can prevent/avoid PM, thats dope. But if you get it its not the end of the world. There are hundreds of methods of attack out there, a lot of people have had the pleasure of dealing with good ol' PM lol.
