I have several orchids from two different vendors. Several of the orchids arrived with pitted and sunken areas in the middle. The underside of the leaves seems unaffected. I have kept an eye on them and it doesn't seem to be growing and I am not finding evidence of mites (at least I don't think I am). Would anyone know what causes this? Is there anything I can do to help the leaves recover? And is this an acceptable condition for orchids bought on line? Thanks in advance for your thoughts.
