Just a tad more info for those not familiar with BER. Typically, in early BER, the pod will get an area that becomes soft and seems watery. It's usually a larger area than in the pics above. On the Big Jim pod, for example, it would frequently be the entire lower end. That soft, watery area may then progress to something similar to the sun scald above and, if left on the plant, will become black. Note that while the name BER means it most commonly is found on the ends, it isn't uncommon to have it start on the sides, instead. And yes, as RogueJim indicated, BER is most commonly a sign that the plants aren't getting enough calcium and magnesium.
