How do I max out 3x1000wt hps?

So this is my first time and I'm going kinda big. I dropped about 3 grand all told on set up, 3x1000 wt hps and a 3x7' terrapot air table pro, fans, ferts, ect... After a bit of a rocky start things seem to getting better. I have 25 "heavy duty" strain on Supernatural nutes. I switched to 12x12, 5 days ago after 2 wks of veg. and they currently stand @ 15-16''. Wondering if any of you have exp w/ this strain and what kind of yield I can expect w/ this set up? Also wondering about this yellowing and mutant 3and4 finger leaves. Thanks guys!

You're burning 1,000 watts to many, bro. If you wanna max out 3K.... you'd have to cover a much larger area (5' x 15'), but I've heard of guys getting 5+ pounds from a 4' x 8' E&F table w/ SOG (3k).
