Hello, I purchased a fiddle fig in October. It seemed to do well in my apartment. However, brown spots have formed on leaf margins, tops, and undersides. The plant gets southwest light. A humidifier is in the room. I water only when the leaves start to droop. I did lightly mist the plant two weeks ago. My limited reading leads me to believe that was a mistake. I really like this plant. Any thoughts? Thank you, D
