small time grow

ok so im growing like 3 plants and i have them sitting by the window where i get max sunlight. they look amazing and are even starting to have the slightest stench. its very leafy and not really budding does that mean its male or does it mean its a weaker strand like regular?

they will bud when the light hours reduce, usually around autumn time. The problem you may have though is light leaking in from your house.
When they have reached a desired size, put them in a 100% dark room for no less than 12 hours / day, after a couple of weeks they will show their sex.
they may double + in size when flowering, so remember that when judging the size.
