Here's the picture of the center of the fan. It's still growing - the green and half dead leaves were both grown over the last 2 weeks.
The lights are on for 14 hours a day most of the other seedlings and the other plants are doing fine with the setup. Temp varies from 64 at night to 68-70 during the day. I have been letting the soil dry some between waterings. I might pull it out and rinse the crown and see of there is anything obvious.
