I've been finding that a lot of my tomatoes have hard, black sections inside them. No pattern as to location and no holes on the exterior. They seem just perfect on the outside, which makes it so disappointing when I slice them open. Any ideas?

Yeah, it's a terrible disappointment. Below is a reference to it:

The solution is the same as it would be with normal BER: even out the moisture levels, correct overly acid soil, and wait for it to go away.

There's a FAQ on BER in the main Growing Tomatoes forum.
