Attic is right...but besides from that point,make sure you oxygenate you soil so your roots can recieve fresh h20,if not the youngins will get root rot and quickly die,also your soil looked extremely overwatered and moist,which will slow growth,deprive oxygen and slowly kill your babies.....a rule of thumb is a slight watering around the base of the stem when the top layer of soil is about dry or dry.....your roots can't grow and penetrate the soil if constantly moist....good luck.
