Hi all. New to this group, so thanks for having me. I recently got this Black Prince and noticed it has some areas with what looks like powdery mildew on it, but I don't think that's what it is. Then when I wipe it off, it leaves like a damaged, scabby area. Does anyone know what is causing this? Thank You!

I don't know what that is, but if the younger leaves remain blemish-free, they will probably just end up replacing the damaged lower leaves. I don't think there's any benefit to trying to clean off those lower leaves, it looks like the brownish parts are embedded in the skin.

Black Prince is normally dark green to brownish black, more the latter in strong light. If your plant is Black Prince, it's got an unusual color pattern. The yellowish hue has me concerned. How much light has it been getting? Have there been any recent changes in its exposure or care? How much and how often are you watering?

Welcome!

I received it a few weeks ago. It came from a grower in Turkey(?). It gets full sun (when we have sun). It is inside my house as I live in Washington State. I water it once a week, if it is needed. I just ordered some Cooper Fungicide to try. I'm hoping that will help. I don't know what else to do except baby-it thru & hopefully it will go away. Sighing!

That would be my recommendation. I think it may simply grow out of this.

The more natural light the better indoors.
