Stonerdanswered grow question 4 years ago As 8thchevron said, those are bracts! both sexes of the cannabis plant has those to protect the future flowers!
It is still early to determine your plats' sex, keep an eye for development in those growth points if small thin white hairs (pistils) then it's a female, if it grows what looks like a sack/banana/ballsack/whatever people like to call it (it's actually called stamen) then it's a male plant.
Beautiful looking plant btw! the main-lining work is on point!!
Hope this helps! Good luck and happy growing :)
