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.

So, I wrote out a long answer and posted it, but it seems to have disappeared.
Anyway, they are clones. The woman who provided them to me had numerous strains, but was somewhat lax with her labeling, and didn't really have any idea what they were. This is why they were free. I did buy two known plants from her, which I will pull clones from for my second grow. In the meantime, these are for "practice", enabling me to get my grow system all figured out before I go to my "good" plants. I did take a few clones from these while still in veg, on the off chance that they turn out to be something noteworthy. From the clues, I would hazard a guess that two of these plants are the same, and that the third, stretchy one is different.
The blue dream and the blue cheese/haze X which I still have in veg, although two weeks ahead of these three plants, have proven to be very leggy. Perhaps the third plant is a sister to one of those. I just don't know.

The CFL is hanging up in the eaves of the tent. I don't think it's adding anything to the grow, but it has its own pull chain, and I have shut it off. I originally plugged it into the timer as a safety precaution, so that it will automatically shut off with the other light, even if I forget to shut it off.

Somewhat unrelated, but I might as well ask. The two mothers I mentioned are now about 3 feet tall, not including the pots(7gallon, 2/3 full), and I'm quickly running out of vertical room in my veg space. My understanding is that clones are best taken from the bottom branches. Can I just top my two plants? Will that have any adverse effects when I go to take clones a month or so from now? I really don't want to have to go through building a whole new veg space if I don't have to.

What kind of pots are they in hard plastic/smart pot/airport square or round? Smaller pot will get root bound quicker and you will eventually have to trim the roots like a bonsai tree. You will want to make sure it is healed from any clones that you have taken if you are going to prune the roots. I'm not sure if you would need to prune roots in a smart pot or not since they air prune roots. I've never kept a mother plant but this is what I gather from what I have read. I can only imagine trying to trim roots on a 7 gal pot

7 gallon round, hard plastic. I just put them in there, up from 3 gallon pots, last week. The roots were well developed, but I wouldn't have called it root bound. I'll probably keep them for only a few rounds, then mother out a nice clone from the last batch I take. After that, I'l just move them outside for the summer and let them do what they will.

I think you're right, I think you have two different genetics or at least two different phenotypes. It's your grow, use the CFL if you want, but I'd only use it for taking pictures. YMMV...

Clones can be taken from anywhere but heavily wooded cuttings are harder to root. Yes, you can root the tops. Just don't cut more than 50% of a mother at any given time and give her time to recover.

I wasn't really looking to clone the tops, just prune them to keep them away from the light. They now seem to be doing that on their own, so I'm gonna leave them be until things change.
Meanwhile. Lots of activity under the CLW. The other two plants have joined in on the stretch and started to flower. I raised the light two inches on sunday. Currently, tops are about 15-16 inches from the light, and main canopy about 20". Coverage seems to be ok, but I have a feeling I am at the limits of the footprint at this distance. The canopy is very dense, and so far, seems to be keeping pretty level. Contemplating giving the girls a trim "downstairs", if you will, but not sure if I should start doing this so early, or wait.

Almost forgot to mention, the humidity has been increasing with the vegetation, and I just switched the 6" booster to constant on during daylight hours. So far, night time is still 15 minutes on/30 minutes off. I'll check the hygrometer tomorrow morning and adjust that if necessary.
I have been using the General Organics per their feed chart: http://generalhydroponics.com/site/gh/docs/feeding_sched/GO-Feedchart.pdf

But keeping the nutes on the "light feeding" amounts for now. I had some nute burn issues early on in veg and its made me a bit shy. At this point, they are taking a gallon each every two to three days , nutes added every other watering. The three pots sit in a plastic tray(the bottom of an under the bed storage bin) and I remove any run off immediately with a shop vac. Works great.
Finally, I'm using 48 hr tap water at ambient temp 60°+.
So far, the plants look very healthy and I am having no issues(knock on wood).
Of course, fully admit I'm a noob, and open to opinions and advice. Fire away.

Hey, you might get a picture of the stems and petioles they look red from a distance could just be genetics or it might be early sign of phosphorus deficiency

Other than that everything looks pretty good. Keep up the good work!

Took a couple pics and did a little research. The leaf veins show no red at all and the color is medium green. The leaf stems are solid red and branches have red "racing stripes". Soil ph is testing 6.8-7. Water is also testing at 7. Last feeding, the nute solution tested as very acidic "4 or less" on the color chart. The G.O. feed chart specifically instructs NOT to ph the nutes, and I have been following that. As mentioned, no idea on the genetics, and otherwise, they still look very healthy, with consistent growth. What do you think?
