actually I looked closer at the picture and see it looks like the seed casing is stuck on the plant, you need to get something like a pair of tweezers and pull it off gently, very gently. sorry, before I couldn't tell, and I'm honestly still not sure, but if you can look closely and see if the seed casing is still on the sprout then you need to do something to help it out now, especially if its been five days. if it had just happened I would say try to give it time to work itself out, but since its been five days, you should get to work asap.
