Should I flower?

Please look at this pic and tell me if you would start flowering. These have been under the 1000w for approx 3 weeks, but prior to that they stayed under a UV lamp for about 2 months.. give or take a week or two. I was thinking about switching 12/12 in 2 weeks. I'm more or less concerned if the stocks are stong enough to hold the weight of the buds. Any info would help.
Thanks!!!

depends on how much room you have. you could flower now or point a strong ass fan at them and let them beef up the stems a bit.

Hope you got like 12 foot ceilings...marijuana plants grow 2-3X there size when you flower them...i'd say top them then wait a few days then flower them...it will still grow up...but not as much and the bottom growth will fill in more...good luck man.

shit those will be some monsters. lol. you should get a fan blowing on them and give them molasses. are you familiar with that stuff?

Whats the recommended mix you give? Should you only start that when its budding?

you can use it through the whole grow.
during veg 1 tablespoon per gallon of water every other watering.
during flowering 2 tablespoons per gallon of water every watering.

Holy smokes your going to have 12ft plants lol.....

start flowering at about 4 weeks, sometimes a tad sooner or later..

no worries tho, you'll just have your hands full (pun) and hopefully with alot of good bud...
