Looks good man, keep up the good work and posts!
Sucks about your little accident, but that shit happens, and the plant doesn't look too much worse for the wear.
I would suggest throwing a couple cfls on those lower branches--even if space is tight, you should be able to fine some kind of bendy lamp (or shop light as suggested earlier) to get some light down there. Just get the 2700k soft white spectrum and it will be a nice supplement to your hps.
I'm running a 150w hps, in addition to 11 23w cfls, 2 24w t5ho fluoros and one monster 65w cfl. My space is 14"w X 30"l x 30"h, with a removable shelf to expand vertical space to roughly 4.5 feet. The more light you can cram in the more bud you'll get.
Good luck though, they're looking nice!
