Thank you all for the helpful comments! I don't have a water analysis, although my other orchids are doing well (I have a variety of orchid types). I will repot in a new pot, and decrease the feritilizer. I'm currently using medium grade fir bark. Does this not give the roots enough breathing room?

One note: I was watering just once a week and I was having the same problem and that is why I switched to watering more often.

Any advice for proper lighting or does it look like it's getting the correct amount?
