leaf damage and strange residue

I’ve had powdery mildew before and this stuff just doesnt seem to be that but I don’t know what it could be. Saw some markings on leaves that reminded me of thrip or spidermite damage but no bugs that I could see. The powder stuff is only on the tips of some leaves. last week I washed it off with water and now its back and almost dusty in the way it collects/disperses. Plant is living in basement.
