Different plant, maybe, or could it be the location in the tent? The light is centered over all three, with the center plant showing less vertical growth than the other two, which I guess is to be expected.
I added a 40w cfl on the other side of the tent as a work light, which is connected to the same timer as the CLW, but at a distance from the plants that it adds little, if anything, to their growth.
Are they clones from the same mother or from seeds?
A CFL isn't going to help much (except for taking pictures) and you're supposed to be evaluating the CLW light not CLW + CFL lights.
