My tomato seedlings are about 3 weeks old. They were looking great until about a week ago. They started to turn purple and droop a little. The first leaves are turning yellow already. Should I be worried? Anything I should change? Here are some details about them…

Burpee organic potting mix.
Watering about once a week when the soil feels dry.
GE full spectrum LED lights about 12” and on for 16 hours.
In my basement at around 68 degrees
I gave them a 1/4 dose of 20-20-20 a few days ago. This hasn’t seemed to change anything for better or worse.
I run a small fan a couple hours a day
