Fast growers, flower or grow?

I'm growing five plants all some random skunk strain and they are growing like crAZy! I'm raising the lights every other day. They're all 1 month and 4 days into vegetative, and I was originally planning on putting them into flower about now.

Should I keep these mad growers going for 2-4 more weeks? or should I put them into flower?
