I'd spray it with a 2-3% h2o2 solution with a surfactant of some sort --yucca or castile oil etc... very important for effectiveness to break surface tension of water. H2O2 may burn pistils a bit -- usually takes multiple applications and some are more robust than others, but it can happen. Their is a chance they will turn color prematurely... not too big of a deal if near end. h2o2 breaks down into water and o2.. so, compared to other options it's fairly safe option in flower... though still something you'd rather not do. the spraying does 2 things for you... it'll sanitize other parts that may not be visibly effective and it will prevent as many spores from going airborne while you remove foliage with wpm spots. picking off dry leaves will just cause a plume of spores to pop into the air, which will easily spread with good circulation. when removing leaves, also remove any other foliage that touches that leaf or can come into contact with it easily. I'd have a plastic bag there while you do it, so again you limit spores in the air while agitating the hell out of the plant material with WPM. i'd continue to spray h2o2 for a few days... right before lights out... in fact, don't worry about spending 10-15mins doing this after lights out... if 12/12 there's more than an hour of cushion you can bite into without causing any re-vege.... or if an auto, simply doesn't matter if you give it a little extra dim light while spraying. Light destroys h2o2 very quickly. It needs 10mins to be properly effective at sanitizing. Going over it twice can prolong how long it stays moist for that to happen. Best option -- if you can isolate it, do it... it will spread. Very rarely will you kill it off, if it is dug in already. you can at least hold it back. i'd apply the h2o2 for multiple days even if you see no signs. it's probably lurking. spray under leaves too. use your trichome scope... you can see a distinct difference if it is on the buds... the trichomes have a net of hyphea over them .. stringy substance on them and not as easy to see stalk and head of individual trichomes. If you see that, i'd cut the buds off and if it's all over the plant, i'd trash the plant. some plants are more robust than others... hopefully you can simply remove the infection and all is well... can happen. The timing and how bad the infection is determines if i go with nuclear option... carefully remove and trash a dumpster fire.

I fought it once with 1 part H2O2 and 4 parts Water. 250ml H2O2 -> 1L Tap water. I spray and then I wash it with a sterilized cloth (don't remember the english word for this...is it "gaze"?). Repeat process untill it's gone.

4part of milk 6part water as spray give awesome result against wpm. usually one application is enough but eventually repeat 2 or 3 times with 10-14 day delay.

First thing is get your environment in check. Cut off the real bad leaves with the wpm. Then spray plants with a mix of water and milk. 4 parts water 1 part milk. spray the plants foliage. Make sure you get it all tops and bottom of leaves. You can even spray buds. Do this for the next 72 hrs. At harvest do a triple bud wash in 5 gallon buckets. 1st bucket water with 1 cup of baking soda, 1/2 cup lemon juice and 1/4 cup of hydrogen peroxide. The second bucket clean water for first rinse. 3rd bucket for the final rinse. Shake buds off and hang as normal. Cheers!
