In hot weather, tomatoes should be watered deeply every day, Shelli. You really can't overwater them. They are demanding, hungry fast growers. They also need a good dose of timed release pelleted fertilizer, top dressed under the straw to get to the roots quickly and last through the growing season. A douse of soluble fert to jump start them growing would be a good idea, right away, too.
Those tomato plants should be 3ft. tall and 2ft. wide by now. You can get them growing, but having fruits on them already, they are showing their stress.
The pepper plant looks fine, but could certainly benefit from a lot more water and some fert, too.
