Mysterious pest/fungus moving through my collection?

[ramonypony]

It ravages new growths but doesn't seem to affect the mature parts of the plants. It leaves behind thick webs and what I can only describe as "granules." The most affected types are my den phals and oncidiums, I haven't seen it on a cattleya yet.

I just found another victim, Encyclia mariae, and it pissed me off enough to try to figure this thing out. I removed as much of the damage I could and sprayed the plant with Bayer Advanced 3-in-1.

Is it spider mites?? I've never dealt with them before but as far as I know they leave pitting in the leaves and tiny webs, doesn't sound like what I'm seeing.
