I can't see anything that would concern me. I curse the fact that I have old eyes, but maybe it's really a blessing in disguise! LOL!

I see what you are talking about and the few times I have seen something similar, the leaf fell off. Like it was broken where it attaches to the petiole, but not completely. Mine was almost always due to mechanical damage. No clue about the circumstances with yours.

I'd play the watch and wait game; if things look worse or don't improve, snip 'em!

Oh wow, there are quite a few :-(

its funny because other than the black color they don't seem to be injured. Ugh!!! This was another Hoya from THAT vendor. Maybe I should take a break from purchasing ...... it must be a sign from the Hoya gods to stop and take care of what I have. :-)

I'm not saying what you have is anything. Just keep an eye out, is all! I cannot find a close-up of merrilli's leaves, so I cannot tell you if is just a normal variant.

Thanks for your help aurorawa .
