1st time grow....looking for opinion

Hi all.....I have just started my first grow. I started a Afghan Kush auto-flower and a White Siberian both fem seeds from Attitude from seed planted 3 weeks ago. The taller of the two is the W/S. My question is the W/S seems really bushy( I'm Pretty sure this is good). I have done loads of reading of all your posts( Thanks....has helped a ton!!!!). I was going to trim some leaves of the W/S then learned about LST. As in the photo I did this this morning. Am I correct in doing it this way or should I cut some leaves back to shed some light so to speak?
My soil is a 50/50 mix of fox farm and ocean. My grow box is 4'x2'x4' with 4 32w full spectrum flo's (6500k) 2 32w flo's (4100k) and 4 23w (5000k) cfl's. I have done nothing except water every 3rd day with approx. 12 oz. filtered water that has sat for 3 days....no nutes. pots are 3 gal. size.
Any input would be much appreciated since sometimes I feel as if I'm in left field with a hockey stick!!!!!!
