These are my plants, they are about 3-4 weeks old. I don't know if they are too small or not. They have been in my closet since birth. I transplanted 2 into better soil, first they were all growing in the nasty muddy soil. I'm putting them outside into better soil soon. Some of the leaves have brown spots on the, idk what that is please help. The very small leaves on all of them have turned brown also.
