Answer: Unfortunately, based on your description I am not able to diagnose the yellowing for you. Sometimes early fall color can be an indication of drought stress, but yellowing could be a sign of a soil deficiency or a pest or disease problem, or even overwatering, too. I would suggest you consult with your county extension and/or a professionally trained nurseryman to try to determine what is causing the color change. I hope it is nothing serious.
