Looks like powdery mildew to me, but low humidity kinda says not.
How much of the plant is affected?
@Knukle just a thinking out loud, if you touch the stuff does it come off on your fingers as a crumbly, slightly sticky residue? Or is it completely dry?
Also, is this only on the top of the leaves? Or is it under also?
Nope no crunchy or nothing i tried rubbing it off and nothing either and most leaves have it.
Most of the plant. The humidity has always sat so low mold was the last thing on my mind. Also I dont spray the leaves so i just cant even start to guess whats wrong it doesnt come off either.
Look on the back of the leaves with a magnifying glass real close and see if there are any TINY black specs. You might even see them move if there are. Also look real closely between each leave for any sign of spider webs. Look closely on the buds of your flowering plant for spider webs. This looks like it could be spider mites to me. I had them at the end of my last grow.
Maybe a dose of Neem oil is in order.
Mites get out the microscope
