Would More Light Help during Flower?

I have 10 ladies in 5 gallon grow bags in a 4x4x6.5 under a 1000w mh right now vegging for about another 3-4 weeks. All strains are above average as far as yield. Normally I just flower in the tent under a 1000w HPS but only downfall is it looks like a Jungle by week 4. This go around I have more room to flower in and I want to get more out my ladies. I feel like i don't get the amount i'm suppose to with 10 plants because I have them all under one light.. I wanna know would it be better and would yield increase a lot if I put the plants out in a open room and put a extra 600w HPS over top of the ladies with the 1000w once I flip the switch? Like i would put my taller bushier ladies under the 1000w and the short indica types under the 600w

Strains: Early BlueBerry, Sour BlueBerry, Grape God, Sage N Sour, GigaBud, Cinderella99, Blue Dream, Cream Caramel, Great White Shark and Grand Daddy Purple

higher intensity light will definitely give you better growth/yield. better light coverage as well from not being so crowded will also increase these so adding that light should give you a way fatter harvest. i try to nearly double my wattage in flower.

I would totally keep what ever is tallest together under one and if there's some shorter stuff keep that together with the smaller light. U would def want the 1000k on the tall ones if u did it that way.
