That looks to be a calcium deficiency. You may as well supplement, both, calcium and magnesium to ensure that the calcium gets utilized properly.
DOLOMITIC lime will be your best bet here.Make sure NOT to use calcitic lime, since it does not contain the magnesium necessary for calcium uptake. A large helping of both hands full of the stuff will be plenty.
With peppers, I would also recommend a little ironite as well. This will help to keep the pH a little more acidic, as well as keep any bad microbes out of the soil. Iron will also help the fruits ripen better/faster.
