If you have room to plant elsewhere, I'd say go ahead and start more, but I wouldn't bother if you're going to put the new plants in the same spot since they'd likely get it as well. You may think about solarizing the bed once it's empty to try and kill off some of the pathogens.

Thanks for your thoughts and the info on solarizing. I've grown tomatoes, which are in containers, for the past
five years in this same area and haven't had these problems. Also, I sterilized containers with bleach and water solution before filling with my mix, too. Seems you think they'll do OK anyway...am I reading you right?
