What spectrum are your CFLs? The bluer (6900k) are best for veg and the yellower ones (2900k) are best for flowering. The 75watt equivilents are about 26w so you got 234w of CFLs thats good but make sure you ventilate all those lights well or it will get too hot. Also you'll need to keep those cfls 4"-6" from the tops of the plant for them to grow right.
