14 gal tubs with 4-5 plants per light

Hey Im using 14 gal tubs and I would like to get a pound per light with a 1k light. Im using Roots coco, and a nutrient line. I pulled from a 4 inch pot on dec 1 and put into 3 gal pot. They are about 2.5 ft tall now, (Bubba Kush). I hear Bubba grows short and bushy, but I want to make sure, if I only have 4-5 plants per light, they each produce well.
Well any thoughts would be great thanks.

good luck.....
