Sick phalaenopsis!

[cabo2847]

Hi! I've had this phalaenopsis orchid for about a year now and it's rebloomed twice since I've had it, but within the past couple months it's taken a turn for the worse. The leaves are quite thin. One of the bottom leaves got small white spots on it and turned yellow around the edges of the leaf. The spots are in the leaf rather than on it, so I don't think it's some kind of pest. Now another leaf is doing the same thing and it looks like another is about to as well. I tried to google the problem but haven't seen any images that match what I'm seeing on my phal. I repotted it and the roots still look pretty healthy (I cut off the few that were dead). Anybody know what's going on with my orchid?
