New to orchid board! vanda problems?

[Hirschy]

Hi! just signed up to orchid board since i recently took the plunge and decided to get involved with orchids full force! for a couple of months ive been collecting different types but have really gravitated towards vandas...
I just purchased three plants from an orchid auction and got them for a steal, however one looks a little sick (then again i have very little experience so who knows!)

there are isolated black spots on one leaf (of about 20) and another plant is a little yellow on the bottom couple of leaves... however it is trying to bloom so i dont know how bad it is..

they are getting plenty of water... every morning ill water them and 15minutes later ill spray them down again.. from what ive been reading they could be getting some more sun since they apparently like some good direct sunlight???
really looking for some advice! would be greatly appreciated!!

was today at the brooklyn botanic garden and they have a lot of Vandas there and for teh most part had very similar spots... seem to be natural. but well I am a novice.
