Flowering starts the day you flip to 12/12. At week 6, I would think they should be bigger but, that all depends on your strain. There's usually a 2 week window where they really pack on the weight though and you might be just getting to that stage. Maybe move your lights closer, with CFL's you can put them within a couple inches of your tops. What strain are they?
