Thanks for your replies. I don't think it has spider mites, but it might have had a little bit of scale at one point, but nothing horrible. I keep a humidifier on inside my grow tent, and it keeps the humidity between 50-90 percent for most of the day. I did repot it into cypress bark mix when I got it, so maybe I should have watered it more after that. I tend to err on the side of underwatering. Thanks for the help!
