Hi! It looks like there are deposits of yellow or grey fine dust on the tops of a bunch of the leaves of my fiddle leaf fig tree. It’s like a fine powder/mineral deposit and I’m able to wipe it off without much fuss using a gentle cloth and some misting. I do not see webbing or any other signs of potential pests, just whatever this substance is. I’m wondering if anyone knows what this could be/whether it is cause for concern (see pics)? Thanks!!
my suspicion is it’s minerals and/or dirt and dust that is left behind after water dries up on the leaves.

Mainly yes. But it could also be powdery mildew - this tends to happen when the fig is in low light areas, so make sure your fiddle leaf fig is getting plenty of bright indirect sunlight.
3 Likes Good to know! It sits in a space where it gets bright indirect light all day so I’d presume it’s not mildew caused by low light and moisture. I cleaned it pretty well yesterday so I’ll keep my eyes out and see if it returns in the meantime.
