I have a seedling that broke dirt a couple days ago but then just stopped at the surface. The cotyledon are still closed and and are yellow with a very small amount of green to them. Did this plant just decied to give up or is this sometimes just normal. Should I give it some nutrients? I know this is a no no with seedlings but it looks like it may be an old seed and may have just ran out of energy is there anything i can do or should i just sit back and wait and see. Thanks
