What is the color temperature of your CFL's and the total lumens? If the color temperature isn't in the red, then it will take the plants longer than they would otherwise to finish budding because they aren't receiving enough of the right spectrum of light to make it happen. Seven to eight weeks is about the time indicas would be finishing up, but it definitely looks like you are running a plant that is more sativa dominant, so I think it just naturally needs a couple more weeks.
The yellowing leaves aren't necessarily a sign that the plant is almost done. It is a sign, since the plants will start taking nitrogen out of the leaves as it begins finishing up bud production, but if you cut off nutrients too early, the unavailability of nutrients isn't doing you any good.
I'd recommend giving a good full dosage of nutrients, and then after that, cutting them out of your watering for two weeks. I would think that will put you right about harvest time, and giving them a good feed now should help make sure they have enough nutrients to use in the meantime.
The fact that you are using fluorescents shouldn't be limiting your bud production, as long as you have the right color spectrum and enough lumens. Obviously, since the intensity of the light isn't the same as an HID, it will only be the tops of the plants that really develop, but, otherwise, the tops should develop fine.

Don't have a fan blowing on the buds themselves. Doing so will dry the surface of the buds too fast and might mislead you to thinking the rest is adequately dry if you don't know how to properly check for that, leaving an invitation for mold. Drying the buds too quickly itself is not good for smoking anyways. You'll want more of a passive air exchange system going, perhaps a weaker exhaust fan at the top of your drying area, with an opening for air to flow in at the bottom. Definitely no fans blowing on the buds. Your RH is like 50% higher than it should be for drying, I would think.
