White powdery spots on Hoya, fungus?
I need help with my Hoya rotundiflora. It's small starter plant grown outside on my patio with lots of indirect light, but no sun, and it got white powdery spots on couple of leaves. It started from one spot (looked as denser fuzz on the side of the leaf) and now is definitely spreading. I checked it under microscope and it's not a bug of any sort, just white tiny thread like growth on the surface, spreading mostly on the "fuzz" and clumping where it started first. With naked eye it looks like sprinkle of flour. I moved this plant inside to get it as far as possible from other hoyas and need help with treatment. Any suggestions will be appreciated. Aggie
