Tropicals & Tender Perennials: Sick brugs, 1 by Joan

I have three brugs that aren't doing too well. Their leaves are mottled and dropping off. I can't see any bugs, but I've sprayed them anyway. This started about 2 weeks ago. Do you think they have a virus? If so, I'll throw them in the dumpster. I have two more brugs that are away from these that I don't want to take a chance of getting this, whatever it is. With only having 5 brugs still alive after wintering them over, I don't want to lose all of them if I can help it.

Thanks for any help you can offer. I'm going to be posting several pictures from different angles.
