I bought the generator.
If the milk wash don’t work it’s a bit expensive and works great tho against wpm. Blue magic. Shit is a beast against wpm. I suffer wpm all summer long inside growing and blue magic saves me Everytime. Usually one good spray takes care of the situation sometimes 2 sprays depends how hard I go on the first spray. If I hit every spot of the plant first spray all will be good just make sure not to miss a y spots or it will spread again fast. Here is a pic of the blue magic bottle and directions. That I know of it is 100 bucks a little bit they do have sample bottles out in 2oz bottles will mix one gallon of water with the 2oz of mix so far I havnt noticed any differences in taste and one plant I’ve used blue magic on 4 days before I chopped the plant. Says safe til last day of flower and all. Basically consists of soy bean oil alcohol soap and a few other ingredients but safe til day of harvest.
