I am having difficulty with this bug. Not sure what it is! The top of the leaves look like nutrient burn all brown on the edges and then this showed up. The white spots on the underside of fan leaves. Could you please give me some guidance .
Thank you

looks like Powdery Mildew. dont see the bug. If its, PM thats mold. Comes from not high enough temps and too high humidity
