It's blossom end rot, usually caused by irregular watering - some varieties are more prone to it than others.

Watering regularly doesn't solve the problem if they dry out a bit between the waterings

I think it's also a lack of calcium.

Usually the lack of calcium is down to the watering regime, in that lack of water stops the transportation of calcium around the plant. Throwing calcium at the plant is not necessarily the answer.
