Your lighting is fine as long as you keep your lights close to your plant. I currently use 3-20 sum watt cfls and they work well. If you wanna get more lights and can afford them get them. the more light the more energy for growth. however there are a few things u should know.
1. U have to keep lights about an inch away from the plant to get the best results using cfls therefore u have to be careful when usig a lot that your grow area doesnt get too hot. Ive had more than a couple burnt tips from just the three cfls.
2. If you dont spend a lot of time at home you may want to keep the plant from growing too fast and up into the lights before u have a chance to adjust the height. The amount of time spent before the plant needs water again will also shorten because the extra heat will cause more water to evaporate so more than a weekend trip could dry the plant out.
Ive also just recently started using paper clips and string to stake and position the leaves for best coverage. I highly suggest it. be careful not to break the stem though. bend it a little first to see how well it bends. then put your first stake above the second true leaf set as far from the main stem as possible. This increases the light coverage of your plants leaves. Then put stakes at evry 3rd node after that and guide the plant from the center to edge of the pot then all the way around the edge and back to the middle as the plant grows. it will look strange at first but give it a good 24 hrs and your leaves should all be turned back up towards the light. move them around and use strings to tie leaves back and get the most coverage. coverage is important when using cfls because they dont penetrate as well as other lights. The energy saving cfls That say like 100w but they are really 24 or something are the better of the cfls because they penetrate more.
One thing u really have to learn when growing pot is to adapt. every plant is different. just as every grower is different. just try things and see how the plant responds. love it and learn from it and itll grow fine.
PEACE
