Ive been finding this on some of the foliage of my autos. They are really close to finishing. I thought it was just bird crap at first because it's not furry or powdery but I've been finding more and in places where a bird couldn't drop on. Some is bold white like this and some is faint. I've never had wpm before but the pics I see on Google don't look like this.

At first I thought the little white spots might be thrips but it's not streaky enough. They kinda leave little streaks on leaves. That bare patch made consider a spider. Some can for a sort of cocoon similar to that. But when I looked closer it seems to have a visual texture like WPM. When o see something I suspect could be fungal I do a "smudge test". Moisten my thumb and run it across the area to see if it might be something benign like residue from a foliar application and such like ash residue from wildfire smoke. WPM has a certain feel to it to me when it starts looking like what I'm seeing there.

I treated my girls today because I think one may be getting it. I think I may have spotted spores on a leaf tip also.

What do you treat with? I've never had to deal with it before honestly. I'm actually just a week or two from harvest (autoflower) ive been iffy about using anything on it this late into bloom. I considered an h2o2 treatment I was reading about but this is new territory for me. I guess I've been lucky all these years

I use potassium bicarbonate. You could go the biological route with Bacillus Amyloliquifaciens (e.g. Hydroguard) but I've only had limited success with it. That's something you need to start early. IMO more of a preventative measure. I think you're well past that unfortunately.
