Plants can sometimes take up to 30+ days to show sex, in my experience the longer the better, most males will show within 14-21 dysI went to 12/12 on lights 3 weeks ago and only have 1 plant budding all are the same age same bag seed.
Just wondering if it is bad
Put a plastic bag over the boy and GET HIM OUT! QUICKLYOK Plants reanalyzed furthest along is male, I will show pics soon others look female
