Do these need transplanted? please help

My plants are 2 weeks old. They are starting to touch the edge of the pot they are in and losing color like they aren't getting enough nutrients from the soil. Do they need transplanted to a bigger pot?? If so what size and soil would be Best? This is my first grow. Also it looks as if one is showing female characteristics. Could be wrong or just overly hopeful

No not even close IMO. Looks overwatered, need to let the soil dry out real good before you water again.

Ok. Does it hurt the plant pushing up against the sides of the pot?

I am no expert. But I would say no, because if you dont over water them and water the way they want they will shoot up over the top of that pot before you know it.
