Bealara fungus or virus?

It looks like Mites to me. That's old damage that's permanent...or at least until you remove the leaf.

Spray with Neem oil early in the am or late in the evening. (Makes the plants photosensitive) and repeat in a week...then maybe again.

Do you see fine webs? Also, use a systemic insecticide such as Bayers 3-in-1. That should take care of it.

Here in Florida mites are a perpetual thing. I spray prophylactically....plus I like the smell of Neem oil!
