Well, I have turned the spray on them a few times, but I don't think it's helped much. Yesterday I bought some Murphy's Oil Soap per this link:

I'd prefer to dunk the whole plant in the solution and let it soak for a few minutes, but they have grown a bit large to manage that feat! Not even the tall water barrels to catch run-off from the roof will be enough to submerge them. I guess I'll mix a solution in my 3 gal. back sprayer to do it. It's definitely mites of some sort, though. I finally was able to see them. Look like tiny little ticks. Nasty. It's getting hotter and drier here and the humidity is dropping as the summer gets going, so I guess the mites are really liking it. I need to throw them a curve ball, I think.
