The first pic looks a lttle crowded, with the third one looking like you could fill it up a little. Was this weeding out the males? I couldn't comment on your set up, but the plants look healthy enough looking at the top leaf structure. If I was to be reeeeeal picky I could comment, but this is your first grow so if your security is ok, just keep going, enjoy it, reep it, and enjoy the results. Don't look for negative comments or change your methods when this far in cause you're doing very very well for a first grow. Get some more pics just before harvest and ask again. All I can say is you must have read about getting into this. When I started my first grow I'd read for soooo long and sooo much my head spun. The results were people didn't believe my first grow was in fact my first, and it looked very similar to yours. Keep going bro, I admire your first effort. Have you something on the go ready for flower or are you to use the room for vegging too?
"Hell'a" nice first grow stinker'! Props to ya'. Looks like a nice clean setup, too. You know, some reflective material(eg flat white paint or mylar) lining your space, will increase the effeciency of your light.
