My husband's orchid which has been established, through some kind off line
emails pictures, as a sarcochilus hartmanii , is now flowering but I noticed
this morning that the petals appear to be getting eaten - they have chunks
out of them so it's pretty obvious [!] unless the rain could have caused it
as they are not protected by any cover.

On the ones which haven't got chunks missing out of them there are some
tiny tiny grey spots, I can't see anything running around on them so what do
I do?
Spray them with something?
if so what?
