We have been growing tomatoes in large containers. Now the tomatoes are producing they are turning black on the bottom and also turning red already but very small. Please advise

Tomatoes with black spots on the bottom have blossom end rot. This is a symptom of calcium deficiency. Use something like this: http://www.gardeners.com/Tomato-Rot-Stop/33-447,default,pd.html Your local supply store may have something also.
