I think they will be fine. Make sure your water is pH'ed correctly and I usually water just 1/2 cup every 3-4 days for the first couple weeks. By week 2-3 I start upping it to 3/4-1 cup. My understanding is, during the seedling stage the plants need the moisture in the air to grow and only a little in the soil. It is easy to drown the roots (deprive of oxygen) at this very early stage. They are trying to get established and can't handle a lot of water while first developing.
