6 1000 watt lights

Hi I am using 6 , 1000 watt lights I am putting 2 under each light and 4 weeks later adding another 2 under each light so for 4 weeks they will have 2 plants under the light and for another 4 weeks they will have 4 plants under them they will be in 75 liter pots what can I expect to pull on each plant or each light? They will be flowered at around 3 ft tall. The strain in 75% indica purple bud feminized ? Heavy yielding plant . Please let me know thanks also the lights are on cool shades and we have 5 125 fans to keep the room cool. Thanks in advance grow room in 10 ft tall 11 ft long and 11 ft wide thanks again
