I live in San Diego, and some of the coffe berries have no seed. Do you know what causes this? Thanks in advance

Coffee self-pollinates but it can still fail and then the seed doesnt develop. I have seen it more in plants with physical issues, and more toward the ends of branches than near trunk – nutrition delivery?
