This is Catfacing right?

[dice]

That does look like mild BER, though. That last pic looks like both: the
dry, crusted, concave areas look like blossom-end scar on a catfaced
fruit, and the just slightly discolored parts look like the beginnings of
BER. Since the "maybe BER" is so shallow, you may be able to let it ripen
and cut it out of there.

I noticed more BER in a cold summer when I was foliar feeding
to get more growth out of the plants, which were not taking up
much nutrition from the roots in the cold weather. Unfortunately, they
were also not taking up much calcium (transpiration was low at those
temperatures), and while the plants and fruits grew with the foliar
feeding, I was not also foliar feeding calcium. This appeared
to be an oversight that resulted in higher numbers of fruit with BER.

(I had chelated liquid calcium, but the soil had plenty, so I did not expect
to need it. However, they were getting extra nutrition through the leaves while
fruit were setting, but not extra calcium, and they did not take up enough calcium from the soil to prevent BER. The fruit simply
outgrew the calcium supply. That was my theory, anyway.)
