I planted a seed 13 days ago. After about 4 days, the first set of leaves opened up. Since then, there has been no growth. The leaves are still green with a bit of yellow in the center so it still seems alive and well. Has anyone else had this problem?
Typically a seedling will shoot up quickly and then level off for about 4-5 days, appearing to not really grow. It is developing its root system at that point so it is growing just not where you can see it. If it doesn't start to grow within the next couple days I would keep a closer eye on it.
