First Grow -- CFLs -- Day 9. Something strange happening?

Hi guys--

So here are my two plants at day 9 in my CFL box grow. It seems odd to me how different they look considering they've been in the same conditions since day one... They almost look like different strains? Plant 1 (Mickey) is about 4 inches tall and only 2 across with narrow leaves whereas plant 2 (Hannah) is about 2 inches tall and almost 5 inches across with big fat leaves. Could I have gotten two different seeds from the same bag? Seems odd

Anyways, let me know what you guys think. Also how do they look for day 9? This is my first attempt, so yeah

Perhaps two phenotypes of the same genotype, or possibly (less likely) they have different daddies.

With bagseed, you never know what you get. They could be from 2 different plants. Some people just grow a bunch of plants and you could have had different weed in the same bag, or like the above poster said 2 phenotypes or 2 different daddies or 2 different mommies. Or it could be the same...you'll know when you harvest.
