Catasetinae leaf chlorosis and curl?

[SouthPark]

Apologies dorchid. I should have written pimples instead of dimples. Those bumps. Those close-up shots may even suggest that condition that somebody mentioned in one of the recent posts --- edema or something, which is apparently benign or not harmful.

But those checks for spider mites etc was well worth the effort. Totally agree that spider mites can be dynamite or explosive on catasetums.

If there's some chlorosis, could maybe give a little mag-cal treatment.
