I wish I had an answer that could help. However, I suggest googling this question, and perhaps speaking to a produce grocer that may have more knowledge. For instance, at Trader Joe's stores, World Market, or even The Farmers Markets. Good Luck!
I think the spots you are referring to are called scale ...many plants from a similar type get this problem when "boron"is missing from the soil...[also the spots are a disease that points to that ...] in order to get rid of the problem you need to rake up & dispose of any apples not to be used ,so the affected apples do not go back into the soil....[ones with spots are still usable for applesauce or jellies ] ...then an area around the tree that is under the canopy of leaves should be treated with compost ...this will put back the biggest amount of nutrients to the soil & tree & should clear up the problem on the next years fruit]
p.s. if you use this course of action,keep in mind that any composted apples with scale will need to be kept off of other fruit tree areas ,also rose bush areas as they are from a similar family origin
Hi,
I have no fruit trees myself, but a neighbor does. I was curious as Fujis are my friend:)
The other answers sound (no pun intended) spot on, but I found a pretty good resource.

I would trust Washington State U. They mention a Green Apple Aphid, & along with some other possible culprits, here's a cut 'n paste:
"Exposure to intense sunlight or penetration of the skin by spray materials also seems to stimulate localized reddening on green varieties or on the green portions of red varieties."

This one has to do with San Jose Scale
Along with Karen's answers & the ideas from Carolyn, I DO hope you find the cause & a solution! Good luck :)
