you need to switch nutes. bloom ferts in veg produces more males.
miracle gro 24-8-16 works great for veg. use according to label.
also, the plant will reach maturity between weeks 4-12, usually closer to six. you can force flower before that point in time.
if flowering with cfl's, i recomend you flower at less than eight nodes, so as to light them better, cfl's don't have good penetration. flowering at week 5 is no prob, but, if the plants are not mature, they won't flower right away.
