I have several types of pepper plants growing now. Every one of the plants has a black discoloration at the joints of the upper stems, where peppers are beginning to form. The leaves and small peppers seem to be doing fine so far. Is this a problem? If so, what is the cause and cure?

The black color is normal for some kinds of peppers. Nothing to worry about unless you see cankers on the stems. Bell peppers often have a purple-black coloration at points where stems meet, but if the black color is a solid black and the area is shriveled, this would indicate the black are is the issue.
