CFL grow

About 7 weeks ago I planted two feminized purple haze seeds. They are by far the most aggressive plants I've ever grown. For the 6 week veg I had them under 3 42watt CFLs and 2 26 watt cfls. I waited until they were 20 inches tall so i could take some good clones. They're wider then they are tall i would say the bigger one was at least 2-2 1/2 feet wide when i switched the lights. My lighting now consists of one 2700K 68W 300W equivalent putting out 4200 lumens and 2 2700K 42 watt cfls putting out 2700 lumens each along with 2 26 watt cfls putting out 1750 lumens each. I've been using a 15-30-15 fertiizer too. In the past week my plants have grown about 7 inches each and now look like bushes lol. So I'm debating whether or not to add more light. If I do I was thinking about buying more 26watt cfls so I could place them around the plant, or should I go with a higher wattage?
