Thank you for reply. I have had this vanda for years now and it's always been healthy and robust and been in the same spot all this time by a window. I acquired a cpl of new orchids and didn't quartine them as long as I normally do which had my mind going to the introduction of a pest. The new orchids look perfectly fine. I did realize that the sun has shifted recently in my windows( I grow them in a sun room with 50-70% humidity) and this year the sun has seemed a little more intense. I have never seen this on any of my orchids leaves but heat damage makes sense as this one is closest to the windows, so I have put up a shade cloth to reduce the light. Heat damage I can deal with so hopefully not bugs.

Please help identify pitting on my vanda leaves.
