Some of my cherry tomato and Cherokee purple tomato seedlings leaves are curling. I have kept up with their watering and weekly or so liquid fertilizer (organic) but could this be from having the light too close? I just moved the light up yesterday bc they had gotten so big they were almost touching it.

Unless it is a disease, it could be environment stress. How much water are they getting? Could be too much or too little. Also sometimes fertilizer can cause it to do that. Sort of a too much of a good thing. Aside from that could be heat (combines with the water issue). I see Alabama and that it’s pretty mild, so the light might be making it a tad too warm. These look like they are ready to be outside to start weathering.
My instinct is environmental stress but there is the possibility of seed born illness. If you got seeds from a very reliable source then probably not that.
