LST grow log

This is my third grow. Many first time things I'am doing different though. I have 15 kali mist and 2 red dragon going 28 days into veg. Will go to flower at 30 days. THEY ARE IN 3 GALLON PALS and are in happy frog soil mixed 3 to 1 with perlite. I'am useing earth juice products and liquid karma. They are under 1 400w ,1 600w hps, with fan. Last time i used 15 plants under 2 400w bulbs. The quality was excellent but the yeild was only 10 oz. That was dissapointing and iam hopeing to get atleast 1 and a half # from lsting the little girls. I'am trying to get some picture up
