For now, treat it as a watering or nutrient issue. This article will help you determine which it is:

But be aware that this is also a sign of a bacteria. It will kill the plant if it has been infected, but I would not assume it was this until after you have tried to reverse the yellow leaves though watering and fertilizing. Here is more info on the bacteria:
