HPS makes the plant want to stretch. To the plant HPS light is like its sunset all day long so it signals it to grow taller. Its good to use HPS after flowering has set in and the stretch is over because the plant wont be able to stretch as much once in flower, and HPS is the most efficient way to get light to the plants so its the best thing to use for flower. You'll get better results if you use a MH in veg, until after the stretch. But you can use HPS too if you want.
You must know what your EC is roughly? How much nutrients are you mixing in the water?
