Answer 1

Unfortunately, your photos did not come through. It sounds a bit like you have a soil infection. This will require fungicides, or solarization, or both for good measure!

Here are some articles that will help:

Make sure that your soil has adequate time to dry out, thoroughly, down to about 2 or 3 inches between waterings. This will prevent future infections.
