Peristeria elata (Dove Orchid)

[thlap]

Hello to everyone

I recently got a peristeria elata. In first I thought I could treat him as a catasetinae. Lot of water in growing season and no water in winter. By search I made I realized that this is not exactly right. I m a little confused about this. How should I take care of him?
Also I can have the plant in the balcony with direct sun?

I am fairly new to orchids but was lucky enough to obtain this Dove orchid. I don't want to let it down. I feed it weekly and water it every 4 days. I leave in east facing window most of the day. I obtained it and it was very healthy and now it looks like one leaf is getting weak and wilted and several others leaves have brown streaks. The one bulb looks slightly shriveled so I mist it with water. Am I over watering or under watering? What should I do?
