gotta say looks like you've got a decent handle on this. Im in the middle of my first grow as well, im using CFLs but my grow space is abit more contained so i only have room for one more plant (growing in a rubbermaid set up) Id veg your girls for a bit longer as it will pay off even more with the lst'ing. But your plants look like a indica dominant plant with some sativa in it. Meaning those bitches have the potential to STRETCH LIKE HELL once you start'em on the 12/12 light cycle. Mines been in 12/12 for a bit over a week and i almost shit myself when i opened up the box after a its first 5 days on 12/12 (mines mainly sativa and they tend to grow taller) . Im talking like...it probably grew a total of 2 feet or so in a 5 day period (this is adding up the length of all the branches growing out towards the light). In the off chance your curious ive been LST'ing myself here are the two most recent pictures of my girl getting tied down.

In regaurds to your crispyness, when was the last time you flushed your girls? i ask because i seem to notice that a common problem among us newbs is not flushing.

also i wanna second the notion to get some kinda ventilation in that room, its so important for the plants health.
