Doesn't look sick.
Wilting can be either from under watering or over watering. You didn't say anything about where you are and what your weather has been like. In very hot, dry weather, plants in pots might need to be watered twice a day. In cooler, wetter weather, watering every morning might be too much. Have the top couple inches of soil dried out a bit before you water again? Do the plants perk up after you water them?
