It could be a watering issue or it could be disease. Under watering and over watering can both cause wilting in plants. Depending on the size of your containers, you should water them when the top 2"-3" of the soil is dry. This could be once every 3 days, once every 10 days, or anywhere in between - it depends on the container and your soil mix.
If it is one of the wilt diseases such as Verticillium, you will see black streaks in the stem tissue if you cut the stem longitudinally down the middle. There is not much you can do for this except to remove the plants and soil, scrub out the pots with a 10% bleach solution, and let them dry. Then fill the pots with new soil and new plants.
HOPEFULLY, this is just a watering issue, though!
