Sexing before flowering

A question from a fellow grower:

Is there a way to tell male plants from the females before bloom?

Not reliably but not to worry a plant isn’t in flower until it starts showing it’s sex which can be 2 or more weeks after you switch it’s lights to 12/12 and so long as males are pulled before they release pollen you are all good
