This is my second year growing tomatoes, last year we had excellent plants but poor weather, causing a massive amount of flowers to be aborted on all of our plants. This year the weather has been much better, we built raised beds (and put in great soil), and I have been more hands on with the garden as a whole. I am growing 6 tomato varieties, two types of cherries, jaune flamme, black ethiopian, big beef and yellow brandywine. I pulled side shoots on all the plants until above the first fruit set, since then I've let 3-4 side shoots per plant go. All the tomatoes are doing very well, with very heavy flowering, great fruit set and almost no dropped flowers. The one problem I am having is with the yellow brandywine. Every tomato that has formed has cracked open in a non-symmetric pattern on the blossom end, always on the blossom end and not a single tomato has been spared. Only one tomato on the jaune flamme (the first flowering branch, which only had one flower has a distorted tomato that is somewhat split on the blossom end) has similar problems, all the other fruits (which there are A LOT of) are doing great. Below is an image...I hope someone has some idea of what is going on here. I would hate to lose all the brandywines as the few I got last year were some of the best tomatoes I've ever had. Thanks in advance and please let me know if you would like any more information.

Air temps in the vicinity of the bloom that are near 50 degrees inhibits complete pollination and part of the fruit develops but part doesn't.

Not much you can do but wait for later fruit.
