Brown Bottoms on Tomatoes
I'm growing plum tomatoes and yellow bell peppers using the Topsy Turvy that hangs upside down. I have them placed in full sun, which they get for 6-8 hours a day. I have lots of tomatoes and peppers, but the tomatoes are forming dark brown bottoms before they can fully develop into even the size of a cherry tomato. Can someone tell me what's happening and how to prevent this?

It is blossom end rot. This article will help you with that:
Your tomatoes have blossom end rot. Get special formulation from garden shop for this and spray it on. I think they said it doesn't get enough water regularly. Must be regular watering; not a lot at one time.
