can a plant stop growing as a seedling without dying?

Hey everyone, I started growing eight seedlings in a rubbermade box with 5 100W (5600k) CFL's a week ago tomorow. I'm using two computer fans for intake and out and the same pots/soil for all eight plants. seven of them are the same size and hieght, growing perfectly with two distinct sets of fan leaves, but one of the eight hasn't grown any further then the seedling stage. It has the flat flase leaves (which came up at the same time as the others) but no fan leaves have appeared and it doesn't seem they ae going to. The really wierd thing is that the plant isn't dying, the leaves are a normall color green and there are no signs of plant problems or root damage. Is it possible for a plant to stop growing completely at this point without actually dying? The only solution I can think of is this since they are from bag seed, it may be a strain that takes a lot longer to develop. But I've never heard of a plant going six days without any sign of the first fan leaves. Anyone had this happen before?

Happens all the time. No big deal. Not every seed will produce a nice healthy plant. Its just nature. You have heard of a runt right? lol You have a runt. If you want to be patient with it, it might still grow up ok. But you might not want to waste any further resources on it. If you've got 8 others, I'd wouldn't bother with it. Happy growing!
