Lettuce not doing so well

I've got most of my seeds transplanted from the vermiculite to the little trays filled with Mels mix.  My Red & Green leaf lettuce and the Swiss chard seem to be dying.  Not for sure what to do.  I keep them under grow lights for 8-10 hours a day.  They kind of went into shock after I put them in actual soil.  On a positive note, my tomato, jalapeno, egg plant and my herbs are doing great!
