Too much light on Odontioda or something else?

I tend to doubt that it's spider mites. I wouldn't think that it would leave noticeable marks in the short amount of time that you had it. But I've never experienced them on my orchids (knock on wood!) so I've really not sure. If you had a bad case of spider mites you would also see some webbing. At least that's what happened when I had them on a houseplant a long time ago.
