This could be caused by either other watering or under watering. Check the soil and make sure the water is penetrating the rootball. Sometimes overly dry potting soil can actually start to repel water and the soil (container and all) will need to be soaked in a tub of water for about 10-15 minutes to rehydrate it.
Also make sure that you are watering only when the top of the soil is dry to the touch. If it still feels wet, you can just check it again in a few days.
