Hi, since I'm super new I didnt want to post this in diseases in case its normal:
I just got a new oncidium (burr. stefan isler 'lava flow') (from trader joes!! they left the tag in and everything) a couple of days ago. Just yesterday, I noticed that if I look at the leaves from underneath so they're backlit, I can see small spots (all over all the leaves). They're really really subtle (I'm just obsessed enough at the moment to be checking each of my orchids over minutely most days). I tried to get some good pics of them. Normal, or disease??? I'd wait and see but I'm worried about letting any diseases get too far and wipe out my fledgling addiction.
(The first shot shows that you can't really see the spots from the top of the leaves, just the bottom)
