I would flower them right away. Especially if they stretch anything like mine just did. Mine were flowered at around 11 inches and are now 32 1/2 inches tall. That's almost triple. If your plants triple you would be looking at 9 foot plants. lol.

Nice plants

Sativagrowin Reviewed by Sativagrowin on . Vegetative to Flowering Question. Aloha, Thanks to all who take the time to reply to my post. I have several plants under a 1000-watt metal halide bulb running 18 hours being fed 6 gallons of water with (15-30-15) every other day. They have been on this schedule for approximately 8-9 weeks.
