I have some cattleyas with the same problem. leaves are having this black lesion. orchids in general look ok and the problem its not in the entire orchid. any suggestions? please!

Maybe a fungal infection? Too cold and damp?

I hope you find the answer. I don't know what that is. Good luck!

If its outside its can be rain drops which rapidly hit the leaf.

thanks for the information. my orchid it´s in exterior hot weather. it start raining a few months ago, so could that be the cause? it´s not in all the leaves and the roots are strong and the orchid looks healthy

Fungus or virus. Impossible to tell without further tests. Always be careful with cutting tools. If flowers and new leaves look good, you shouldn't worry too much.
