I have just received my first ever Bulbophyllum grandiflorum. I got in in the post yesterday from a German vendor. It spent no more than two nights on route. I noticed this morning that it is developing a suspicious dent in the biggest leaf. It is depressed and pale in colour. Is this some kind of virus or could it be shock of some kind?

This is the plant yesterday after I unpacked it.


This is it this morning
