Is this the start of powdery mildew? One small leaf at the bottom of the plant was really white and you could whipe it off easily with your dry finger. Pictures are taken without flash.
Man Wife thought she had some on her outdoor girls.. turns out the birds just pooped on it and when it rained it just made it look like that.. *lol* But it looks like that might be some powdery mildew.. you can always give them a bath after you harvest to wash it all off but damn.. sorry man! happy growing!
It also makes a more seamless pile. Under less magnification.Just looking like a white "patch" where in a cluster of trichomes no matter how dense the cluster u can still see each trichome individually. They dont become a "pile"
Definitely looks that way. If u could wipe it off I'd assume so even more. If u have some sort of magnification PM looks like antennas and stand out among trichomes.
