If the stocks are very stretched out between sets of fan leaves, then they need more light. If they are short and the growth is "stacked" then they have enough light for now.
CFL's dont penetrate very well so when people grow with them they use tons of bulbs and reflective walls (dont use aluminum foil because it will cause hot spots).. If im not mistaken they need to be within 6", anything farther than that will need an additional bulb.

You should post pics! :thumbsup:

Heres a pic of one of my plants at the beginning of week 3, it has more than enough light (its outdoor) and it has "stacked" growth..
