I had germinated a seed on June 1st and planted it, and then two more on June 15th. So far they are all around 6 inches tall. They all look really healthy. But its been over a month and they look really small. I know they are growing because I'm seeing true leaves form but its growing at an extremely slow rate. My plants are under a 400W LED full spectrum light. I think I am doing something wrong but am unsure. Can anyone help me out? I am willing to show pictures if requested.
