No i'm not giving them fertilizers but the sprout i'm talkin about is my newest on and it is about an inch or less tall. The leaves are completely folded up and the tip of the sprout hasn't even straightened out yet so it still looks like a hook. One leave is sort of dark and not atl all green but the other one opposite is green. The seedling that popped out came out of the dirt without ANY seed part connected to it. So i don't know if this is why.
Also this one's stem is white.
