From now on I'll post individual pictures of each plant. I'm slightly confused with a couple of plants. Harmony (Pic 1) has weird crinkled leaves. The color is great and it doesn't look like a fert problem as the MG Seed starter barely has any. I worry about over watering because when I did their transplants at the end of week 0 the soil held a lot of water. However, the leaves feel dry to the touch and not limp and I am waiting for the soil to dry before I water again.
The temp of the room is hard to distinguish because it is in the basement. The temps outside are around 30F now. I have a thermometer at the top of the cab and one right with the plants. They average around 76-79F. However, the water I use on them stays in the room and it is fairly cold.

Does anyone know the symptoms of soil which is too cold? I raised the platform they're on off of the floor in hopes to treat this problem.

These are all seeds from the same bud so I don't understand the huge difference in their growth rates (pic 1&2 vs pic 4). The leaves seem to have a naturally pebbled look. Maybe I'm worrying about nothing. Some of the plants seem to be thriving while others seem to be asking for help, as am I.
