Thanks for the info everyone. For puddlecruzier and bejay, you mention lowering the lights. Normally they are lower, about 3 inches above the tops. I was going at about 1 inch, but I had 2 of them grow into the lightbulb during the night one night and get some minor burns before I got up the next morning to see that they were touching the bulb. [A side note for all those posters who say a CFL won't burn the leaves even if they touch it - I have 2 plants that prove otherwise.] Anyway, I raised the lights for the picture just to get a good feel for just how little room I have to work in and how short I need to keep the plants.

For Scarlet, yield (at least per plant) isn't a concern as I'm only growing for myself. In the future I won't have 5 plants growing at once, then yield will be a little more important. I did the max I had floorspace for this time because I really figured I'd have killed at least 2 or 3 of them by this point on my first grow.

If I flower before they're fully mature will it have any effect on the quality?
