Too Early to Determine Sex?

Hey copy cat Im growing blueberry og too :) Erm unfortunatly it is abit early I mean I would guess its female but would be a wild guess usually after the lights have been switched for a few days you will know. What you can do if you unsure and you really need to know and dont mind stressing her abit you can switch the light cycle wait for it to show its sex and then put back on 18/6 it will take a few weeks but if you really need to know you need to know and i understand the reason behind it too as nobody wants to waste money on males unless they are breeding lol best of luck bro your doing great anyway next time grow a different strain and dont copy me 😂😂😂 Only joking grow what you want hahaha
