It’s hard to say just by the picture alone, it looks like maybe the start of powdery mildew, there is a possible chance it might be a nutrient deficiency or pH problem, but more likely I’m thinking it might be a critter like thrips.
Cankerous Lesions & Browning
I’ve had a spider mite and gnat problem but have sprayed with a rosemary oil solution once every 7-10 days and it keeps the bugs at bay. However, when I was inspecting a dying leaf, I found a cankerous lesion on a leaf vein. I need to know what this is in order to treat it.
