Greetings @solominer ,
This can happen with tomato plants as well....one of the major problems with growing any plant is over watering and gnats as well.
However since there is new growth on these plants and it looks healthy...you may see quite an improvement in just another day or so....if not then I would indeed start over.
Wishing you well in your endeavours.

Hey there, yes we actually had that problem over the summer. we were over watering the tomatoes.. but once we reduced the watering they started to do much better.
True, I need to keep an eye on that new growth and see how much it improves day by day. thanks for the input.
