Got it, Thanks Jim, and Ursula you're right of course. That's what it is.
I first read the UF article on this, but they also had a link to the article on the AOS site here

I cleaned the whole plant with a soft cloth soaked with Neem oil solution and isolated it. So far, no other plants seem to have any signs. Now repotting and chemical warfare shall commence! Onward!
Just what I needed when I'm leaving town for a week, next Sunday! My bro will be here but knows nothing about plants so . . . will have to treat them just before I leave, then hope for the best.
