"Blossom end rot begins as light tan, water-soaked lesions on the blossom end of the fruit. These lesions enlarge and turn black and leathery. The cause is thought to be a combination of cold temperatures or excessive heat during blossom set, and fluctuations in water supply. When these two factors occur simultaneously, calcium often becomes unavailable to the plant. Hence, a calcium deficiency occurs during fruit formation. To manage the problem, fertilize and water properly. Avoid setting out transplants too early in the season. Use mulch to help reduce fluctuations in moisture levels."

I have added some homemade compost, compost pictures/design to come, to the plants. I have also trimmed the plants. We will see what happens.
Update 8-13-11
I have removed two of the Roma Plants. The other infected Roma is holding in there. There is one beef steak tomato planted that seem to have the same problem, but it is still producing tomatoes.
