Answer: If the "spots" are corky and raised, then it's most likely scab, but I can't find reference to any diseases that make the fruit turn hard like that. If it is scab, you can control it without having to sacrifice the tree. To get a positive i.d. of the problem, contact your county cooperative extension office (ph# 323/838-8330) and ask for directions for getting a diagnosis. Good luck to you!
