Dendrobium, west facing window, 1 " faux blinds cracked about 1.5 inches
open. Plant about 6 inces from blind

Has that brown / red sand look like a spider mite infestation, but high
power magnification shows no mites, and it does not run or rinse off. Close
viewing looks like pitting of the leaves
