I can’t believe I forgot to update this 
After many, many, many different products. After probably $500 wasted. I finally found the best solution for WPM. It’s JMS organic stylet oil. It’s odorless, tasteless, doesn’t nuke your plants, and useable right up to harvest (no, I didn’t need it that late).
A few applications at the first sign of wpm, and it basically disappears. I have had to give another application during flower once, but I noticed zero impact on taste/effect.
If you find wpm it’ll be the best money you ever spend.
I wish I’d found it sooner.
