6 weeks in 12/12 and no flowering

Hey people,

Three of my plants in the closet have been through a veg period of about 1 month+ and then I put them into 12/12 six weeks ago. Two of the three are flowering nicely (for a first grow imho but the third one only grown bigger and showing sex but not flowering.
Is this considered normal and he will catch up eventually?
Anything I can do to trigger flowering?

I have a similar story with another two flowers, these are grown at 12/12 from seed and are six weeks old - one is flowering really nicely while the other have gone through and accident where his head was cut off. Now he has 4 heads but isn't showing signs of flowering.

If anyone is interested I will post pictures later today, when the lights go up.

Thanks,
David

Will HE!! unless you want seeds there shouldnt be any HE'S in the room, Id watch that plant may hermie...

Hi sticky,

It's he as in a flower, I call the girls flowers.

Anyone else can give some advice?

Thanks,
David

If your sure it's a girl, then leave her be for a while. How often are you watering and what light are you using? The problem(if u class it as a problem) with growing from seed is sometimes you get different pheno's, which i suspect is what your have.

Yes, probably different phenotypes...
I guess you can never know, it might just flower well in the end, so give it more time, right?
I'm using a dual spectrum 250w HPS and I water when the pot gets dry - about every 10-14 days.
The strain is THC bomb from marijuana nl

Maybe it's time to start researching about cloning..

Thanks,
David

wow every 10 to 14 days bro i water every 3 days

I don't want to over water them, and the plants look healthy too. I read many time here on the forums that it is advised to let the pot dry and only then to give water.
Or maybe my plants don't like to drink water?

um dude all plants like to drink water just saying bro i never heard of anyone going 2 weeks between watering

LMAO 10-14 days WOW

Did you check your timer? Can always lower to less than 12 hours on.

If the other plants are budding on schedule then the first thing that comes to mind is that the plants in question are pure sativas,its worth the cost to spend a few bucks & use clones next grow.

Throw that plant out this happened to me once and the plant never flowered at all
