m0useanswered grow question 2 years ago I cant tell right now. One pic if i look at it weird kinda looks like maybe a pistil but it could also maybe be a new leaf, it just needs more time.
I would wait a bit more before you make the choice to kill it or use it. Typically the sex should start to show aorund week 5 to 7 for me, it will show pre-sex traits in females "pistils out of the stems and joints" and if its a male it will start to grow balls. These will be more noticeable, they grow in packs and tend to be football shaped or like a coco pod.
familiarize yourself with swollen calyxes as they can be mistaken for balls quite easily and sometimes people will kill a plant thinking it is a hermi.
Best Of Luck!
