Flowering Confusion

I Have 3 Silver Haze
2 Northern Lights And
3 Big Bud Plants, How Long Does Each Strain Usually Take To Show Their Sex? I Have Been Flowering For 3 Days Only And Can See Them Showing But Too New To Tell Or I Just Have Untrained Eyes To Spot...Does Balls In The Corner Means It's A Male/Female Somebody Help Me Out.

balls means male...males generaly show sex before females but plants can take a couple days to weeks before showing any signs of sex or flower.....

plan on giving you plant a full 10 days or so to show sex. sometimes it will be sooner, but nothing has ever shown sex in less than a week for me.
