Sansai Blue with questionable black speckles/spots on leaves

[Sammy]

Hi,

I have 2 phals, 2 paphs (or slipper orchids), 1 Dendrobium and 1 miltonia and am looking after these just fine.

I was after a Vanda for my birthday and was lucky enough to get one, a Sansai Blue. Needless to say i love it to bits. It came from a florist who has apparently had orchids for years. Yet when it was presented to me, it was dusty and the leaves looked pretty crappy. I cleaned the leaves with a damp tissue and the plant looks a lot happier now.

But upon closer inspection i noticed there are a few black bits on the leaves. A couple (litrally 2 or 3) black almost round dots and a few black speckles around the tips of a couple of leaves.

Now i have been looking all over the forums for some sort of definate answer, but figured getting pictures was the only way to get the best of all your brilliant advice.

My mum, (bless her) took it back to the florist who cut the bottom two leaves off (they looked a little ropey) and said there was no chance it could be any type of fungus.

What do you think?
