Vegetable Plants Wilting, Too Much Water?

If they all wilted at the same time I would say definitely, have the leaves curled down (too much water) or curled up (not enough water) have the leaves turned yellow? You might want to pull 1 and see if the roots are rotten, what about raised beds in the future. You may want to try digging a hole a few inches away from the plant and see if that fills up with water if so you are definitely saturated. . Or you may have root knot nematodes. If you like you can send your rain my way, we are starting water rationing at this time I could only save 150 gal. of rain water this year and I have used most of it already.
