I think its a boy "need help"

Am I understanding this right that on a indoor grow you don't identify sex until well after you've already put them on a 12/12 flowering light cycle?!? Sorry, don't mean to be a total Noob, my only experience at all is outdoors.

Depends totaly on the strain.
Usualy males show preflowers(clusters) around 3weeks to 1 month in vegging stage.

Females usualy show only after changing the light schedule about 2 weeks into flowering depending on the strain
