Take a look where the leaves were cut. Is this a female? Sent from my iPhone using Grasscity Forum mobile app
Can't tell for sure because of the blurriness of the pic. Just keep an eye on it. If it's balls, it won't take very long at all for it to become apparent. I see pistils in the first pic clearly in the spot where the female shoots out the pistil, but the things you're concerned about there make me hesitant to say. Look the rest of the plant over real good and see if there are anymore on it like this. If there are, you've probably got a male going there. If this is the only place on that obviously decent size plant, then I'd go with female. LOL They generally show sex at about 8+ weeks of age regardless if you flip them for flower. This looks like a nice mature plant but you don't mention exactly how old it is. TWW
