Can someone PLEASE help me! This Hoya black margin is my pride and joy and has a sport mutation that I've been babying for months now. I sprayed it with sulfur a few days ago to treat for flat mites, but I noticed all of these black spots (little holes) all over my plant today with purple edges, and the leaves have extra black spots on them (not just edema).
I'm assuming it's fungal or bacterial but I don't know what to do or how to treat it and I really don't want to lose this plant. Any white powdery stuff you see is left over sulfur. I am desperate.
This Hoya is growing in coco coir and I water it when the top inch or so is dry, or when the pot feels light (about once every week and a half). Pot has drainage, plant is under barrina t-8. I primarily grow hoyas and am very familiar with edema, this is not that.

She’s been through some recent stress I am not sure I would stress her more with more treatments. Can you cut a leaf to prop and just baby the plant for a bit? Monitor it for spread of course. It’s dark here but I can check my collection tomorrow and see if I see anything similar to compare.
Give it a bath, it’s suffocating, 3:1 Water:Hydrogen peroxide, spray down the leaves, then gently dry leaves with a cloth. The Hydrogen peroxide even helps oxygenate the soil as it runs off. Give it a few days, with light, if you don’t have an LED panel, use the brightest bulb you’ve got!
