spliting heads?

Hi, i was just woundering about how to create 2 main colas. and can you do more then one?
i also have another question i have 4 plants (just some regs since it's my first grow) i've been flowering for about 2 weeks and only 3 out of the 4 have pistils the fourth one shows now sign of sex or anything and it is on the same 12/12 light cycle as the rest. what does this mean??

thanks in advance

cut the cola off clone it so you dont waist it and right where the cut was made cut down a little but to much just cut about a half a centemeter down

Some times it takes a few days for them to show there sex. Most show around 2 weeks into flowering, although some take 3 weeks.

You would "pinch" off the cola and 2 shoots would grow from the one spot. But you're already flowering so i dont know if i would do that. It may just stress them hermie, or effect you yield (making it less). Normally when you pinch you do it during the veg cycle so that it has time to make up for the "dammage."

no i'm not going to do it now but on my next grow. thanks for the info. but now i'm a little confused i thought when the pistils actualy come out that's when you count how many flowering day in that case they've been flowering for about 4 weeks

You should see pistils in the first 2 weeks and have nice clusters of them by 4
