Big Bang by Greenhouse Seed Co.

I was just about to run 64 plants, approx 1.5 foot tall, all topped. They are in 5 gallon sunshine mix. I use mostly advanced nutes, they will be under 4k HPS all Hortilux bulbs. I will be running 16 plants under each 1000 hps in a 4' by 4' square, totaling 64 since I have 4 squares. I never have grown this strain, looking to find if they like light, moderate, or heavy feeding. I am kicking them over today to 12/12 cycle. Plan on 8 weeks and 1 week of flushing. My concern is people are saying the yield is low, is this so of this strain? I have been running mothers finest by sensi seeds and average 2.0 ounces per plant on 64. In the same room and environment. 128 dry ounces total, is big bang capable of hitting at least that? I need a heavy producing strain, without loosing to much of potency. The room is a sealed room at 78 degrees F and Co2 is 1100ppm. I use ro water twice a week once to feed, once for just micro. If someone has a good suggestion of a strain for commercial use please let me know. I am a avid grower, so I can do usually well even with the tougher of strains. I also clean the first 6-8 inches or so of the bottom of plant, all topped and staked. I would really like reassurance that someone has hit at least 1.5 Oz per plant average with this strain, in soil not hydro.
 
Checked it out but Im running SOG so my growing techniques are going to be different than that huge bush they have, but thanks again.
