Photo taking tip: Stand back, at least another several inches to a foot from the target.
I guess they don't look that bad (not for a single CFL bulb anyways), but I bet those buds are quite fluffy\airy. In a pinch you could just get a few more of those CFL's to finish them, it isn't worth it to cut so early when you don't absolutely have to (4 weeks isn't enough bloom time). You could use [virtually] as many CFL's as you can\want, it is just that they are somewhat significantly less efficient than HID lighting is (i.e. it is going to cost more money to run them) and high wattage CFL's do indeed get hot.
Don't necessarily listen to everyone telling you to go with strictly high pressure sodium lighting, as metal halides are great as well... they actually put out more PAR (light that plants can harness for photosynthesis) and more closely mimic the spectrum of sunlight. A good HID ballast will allow you to run both HPS and MH bulbs. If you just want to grow for personal and don't smoke a lot of bud, 250 watts is the minimum I would recommend, for one or two smaller plants. If that is the case you probably don't need any high output ventilation or even an odor filter. Consider your environment and personal situation of course, but a small HID light may be cooled with a regular duct fan (a 6 inch, 250 CFM booster for instance) and a couple plants aren't likely to smell very much.
