growing sunflower hydroponically

hey all,

Right now I'm growing a mammoth sunflower hydroponically. So far its doing really well and grew to about 2 - 3 feet. If I were to change my light bulbs from 6500k to 2700k warmlights will the flower begin to bloom right away and stop growing?

Reason I ask is because I remember reading the 12/12 method were people start their seeds with warm light which results the plant to begin its flowering stage right away. The plants stay short because it skips the vegetation stage but it would flower.
