This sounds like shothole fungus, from the description. This will be made worse by watering more. In fact, this is usually the cause of the illness.
I recommend applying wettable sulfur and dolomitic lime to kill off the infection, and repair the pH of the soil.
Only water when the soil is almost completely dry, or really just during dry spells.
