Maybe signs of Powdery mildew, do i chop it now?

i don't see it... initial colonies would be round blotches - little fuzzy / not smooth. Most of the time you'll see it on leaves before it can settle in elsewhere with greater exposure over time. on trichomes, it's usually a much more advanced infection... you'll see a net-like material over the trichomes and they look a little melted or bogged down as opposed to seeing individual stalks and bulbous heads. I don't see any colonies starting... got a trichome scope? if you see individual stalks/heads and nothing growing over it making it look fuzzy, you are good. FYI all the anecdotal remedies for WPM are utter bullshit.. none work. foliar applications will just spread it around.. if oyu do run into it, cut it out ASAP and hope it hasn't spread. By the time you can see a colony, unfortunatley, it is already propagating. Even commercial-only available fungicides are relatively ineffective. Fungi are a robust species.
