Colour Temp of bulbs.......???? 6500k?? They look bright? Run 2700k for flower.....Good luck
Simple short answer to your OP is NO, Not enough light, plain and simple. Also if you are going to add more cfl's add them around the foliage of your plant not just above it. Cfls are horrible at giving off intense light so you need the light 1-3 inches away from the foliage to do any real growing.
23w of light =23w of light.
Yes, 23wx4 bulbs = 92w, but light intensity will still only be as intense as a single 23w bulb.
