Does this look like powdery mildew?

If it tastes really funky and harsh, I would not smoke it.

I agree, if in doubt throw it out! (BTW, isn't all dispensary weed funky and harsh, LOL).

I just thought this leaf looks splotchy white. I know it's not the clearest I just don't see much trichome resemblance. Something looks off I feel like.

If you're seeing splotchy white on sugar leaves of cured buds, and you looked at it w/ your microscope, and it's not trichomes – I'd say toss any buds that look like this. Also smell them... mold has a distinct odor.
