Just bought this beauty at the orchid show here the first weekend of February and saw this spot today. I haven't repotted the new ones yet since they're all in bloom & I also realized I was low on potting medium so I was waiting for that too.
I've been lucky and haven't had to deal w/ too many problems in the past year beyond pretty run of the mill issues. Can anyone help me diagnose this?
Could be cold. We've been working on the sunroom and having to leave the door open. That's a good point. Didn't think of that since I was so careful bringing it home!
