I noticed that my phal had a spot on one of it's leaves about 6 months ago. Now there are around 10 spots. It doesn't seem to be affecting the plant but the spots are spreading. Is it a bug or mite? If it is, what should I do? I don't want to remove the leaves because it barely has any. I hope the pictures help.
the translucent spots look like they might be from sucking insects - I'm not sure what insects do this, but most of my outside orchids get these - especially the thinner leaved ones ...
The convex looking spots, I don't know what that is -
If this were my plant, I don't know I would be too concerned at this point - tho I would keep my eye on things ...
