Mark - Glad that you are acknowledging this issue. However, I tend to think it's immobile nutrient deficiencies that are induced due to cloudy weather and low mass flow. If you run tissu, water and soils, I have found it's typically a combination of Calcium, Magnesium and Boron deficiencies in combination in the tissue and the fruit abortion is exacerbated where soil sodium chloride or water pH and bicarbonate are issues. Monterey and other day neutrals that share similar genetics are particularly prone when loaded up with fruit - Portola is not as bad in summer plantings. Cheers.
