1st time grow cfl not flowering ??

my friend been growing early durban under cfls, they are 3 weeks old in the pictures,im going to get new pics to post later,
they are now around 6 weeks old they are grown from female seeds.
they have been under 12/12 now for 8 days & are not showing any signs of flowering is this normal????

this is his 1st grow they have been given canna coco feed.
should it take this long to flower is everything ok???

any help would be much appreciated..

make sure there is no light getting to the plants during the 12hr dark cycle and hang on it wont be much longer

its in a growing tent its totally light proof. do seeds take longer to flower as opposed to cutings ?

yes cuttings are the same age as mother

hes got another plant the church strain anybody grown that ?
it smells good like a deep strong weed smell.
