Black Spots on Epidendrum?

[ChickadeeGambeli]

Three questions about three orchids!
I'm most concerned about these black spots on my Epi. Ibaguense. I bought it with a few very small ones that I was told to pay no attention to. I've had it for half a year, and suddenly the spots are multiplying, getting bigger, and two leaves have yellowed and wrinkled and come off. When I removed them, there was a dense collection of small spots under the skin that had been covered.

I just bought some Fungicide with Neem Oil by "Garden Safe" that I hope will be safe for orchids, since I've heard such good things about Neem oil.

I'd love to learn about what's going on and get some tips on how to treat/prevent! As far as I know, I do not over water- never had a problem before.

On my big phal, the lighter spot is an old scratch, I'm wondering about the brownish sunken bit: http://i154.photobucket.com/albums/s...hidwoes010.jpg

Lastly, is this a healthy oncidium intergeneric? You can see some cinnamon dust, I'm more curious about the state of the pseudobulbs with deep wrinkles: http://i154.photobucket.com/albums/s...hidwoes014.jpg
