Those a lovely plants. They look stretched and they are growing slowly. Both conditions may be due to insufficient light. Get the CFLs as close to the tops of your plants as you can. An inch or two away is good. Conventional practice is to grow each plant in a separate container. A single container shared by multiple plants can promote root competition and make transplanting more hazardous. The mottling on the leaves of the plant in the last picture indicates stress. Stress can be brought on by many different environmental factors, one of which is insufficient light. Large swings in pH can do it as well. Or excessive heat. But, hey, they are alive and they're green. Good job. Keep going. Put more light on them if you can manage it. You should also have a fan gently blowing on them. Good luck with your grow and welcome to Grass City.
