Sounds like blossom end rot.

Calcium deficiency. You can spray calcium on the flowers as well as using
soil additives.

Each year, my tomatoes have a black rotten spot on the lower side that
ruins
half the crop. Does this indicate some kind of soil deficiency; if so,
what.
Also this year, I plan to use black plastic sheet mulch with pine bark
mulch on
top of that. I haven't ever did this before so I can't predict the
results. If
nothing else, it looks good and keeps the weeds out.
