First Grow West Coast OG Autoflower

Learned something new on my first grow. Don't turn the fan in in the tent too soon after the seeds sprout. I killed one of my nice little plants. The other seed that never sprouted in my 4 plant grow finally sprouted so I think I may have 3 plants after all! So here are some updated picture of the 2 plants that are toward the end of their second week and of my new little sprout. Not sure but the leaves look a little purple/green. I've barely watered these. Only about a little over a 1/4 gallon of distilled wal mart water that's it. Nothing else. I have kind soil on the bottom, roots organic on top of a 3 gal cloth pot.
