They do, naturally, experience a dormancy through winter. This will, likely, resolve itself in the coming months. Otherwise, it could be stress from overwatering, or too much sun. I would suspect watering to be more of an issue, though. It is necessary to let them dry out, at least, down to 1/3 of the container, between waterings. They do not tend to like to remain moist. This is, especially, true through dormancy.
