Thanks Roberta, exactly. I have been looking at the plant for about 30 minutes with my magnifying glass for about and can't find anything. I have had scale on a couple other plants, but never this kind of chlorotic spotting. Do some plants have a worse reaction to scale bites than others?

I'll alternate Bayer 3-in-1 and Azamax as you suggest.
