Your plants are most likely that small because they are under inadequate light. Bump it up to at least 8 cfls, 11 plants are gonna want a lot of light. Whats hte square footage of you area? A 23 watt cfl puts out about 1400 lumens, and at least 5000 lumens per square foot is optimal.

Also if you start each plant in its own pot, when you re pot you wont run the risk of breaking any roots. Transplant each plant into its own pot asap and try not to break up any roots.
