Seedlings ?

[blackjack999]

I have 24 seedlings started dec 25 5 different strains.They are 18"+ have 7 to 8 nodes per plant nice bushy plants under T5 lights.About 2 weeks ago I changed the light cycle to 11 hours to trigger flowering so I can weed out the males.There is no sign of flowering.How long to show sex?
Thanks For any Help
