Can you tell if a cannabis plant is male or female before flowering?

While there is a lot of anecdotal evidence on differentiating males vs females early out there, it’s either incorrect or unreliable. The only easy way to tell if a cannabis plant is male or female before flowering is to do molecular DNA testing. You can do this as early as 7-10 days after germination when you can take a piece of the leaf without killing the plant.
