Hope things are improving! :thumbsup:

The best advice (that many people gave me, but I seemed to overlook its' importance) is to find a very light seedling starter mix. It will absolutely improve the overall plant health in the early stages. I had 4 week old, stunted, light yellow seedlings that were on the verge of death. I performed emergency transplantative surgery :jointsmile: into some starter mix... within 24 hours the green was back and growth kicked into overdrive. It's all about getting them as healthy as possible before that first transplant into real soil and larger pots. Good luck and keep us posted.
