1) Don't water it every day.Let it dry out before watering again.Mist it occasionally with a fine spray and rainwater.
2) Only use RAIN water or boiled water,they don't like straight tap water.If the water can be warm, even better.
3) Keep above 12 C if you can.
4) They prefer to be away from a window and not in direct sunlight- East is ok, but on a shelf near the window/behind a net curtain will be even better
Tim, I suspect your orchid is being killed with kindness. Stop watering it, let it dry out a bit, then mist it occasionally…it will need to recover. They do loose their lower leaves as they grow and they go yellow before drying out and then you can remove them, but it sounds like it may be protesting at being too wet if watering is happening daily! Also important to use rainwater or pre-boiled water for watering and misting.
Oh- and an occasional ( very occasional) drop of orchid food in the water.
Hope that helps!
