I did some research about pollination. That's exactly what's happening. Just looking at the pictures and the difference between blossom end rot and poor pollination...
Last year we had bees swarm our house and tried making a hive in our house. We were forced to leave and had to bomb our entire house. We picked up hundreds of bees. I know it's horrible to kill bees but it was the only way. We contacted a bee keeper nearby and he couldn't help up. So having bees scares me lol. I'm afraid they'll come back inside. My son is allergic too..
