I got a sharry baby last year. It already had some very small black dots (the man at the greenhuose said was nothing bad) on the leaves which were green and looked healthy.
After a summer outside mostly in complete shadow (only a short sun exposure almost at sunset), the old leaves are full of this little dots and start to be yellowish.
I think the plant functions are ok since in the same time 2 big new bulbs came out, please excuse my ignorance in orchids stuff but do the old bulbs produce spikes or new leaves?
Does anybody have an idea of what to do? I hope are not some kind of fungus since I just got a new orchid I m afraid it will go on the other plant too.

Thanks
