I agree. Shallow watering will cause salts build-up in the soil/potting media. High concentrations of salts in the soil cause water flow to actually reverse direction (because of osmotic potential), in effect the water and dissolved minerals in the roots of the plants move out of the plant and into the soil - instead of the other way around. So the plant is not getting enough water because the roots won't take it up to where it is needed. I recommend flushing out excess salts with 1/2 cup 3% H2O2 mixed with distilled water to make a gallon. Pour this mixture on the soil until you see water running out of the drain holes.
