This can happen when the plant is over watered or under watered or if it has a fungus. Make sure that the plant is getting enough water but that it is not in soil that is overly wet. Treat the plant with a fungicide. I like neem oil as it will treat for both fungus and any pests that may also have started to attack the weakened plant.
