Yup now, you know how to spot it. I have read that males still have a THC value, and that you could use them to make canna-butter still. Then it wouldn't be a total loss, you learned how to grow a mj bush, as they look very healthy in your pic, and you get a nice body buzz off some butter. I know its a heartbreaker brother. Next you will have a wonderful female plant flowering, and out of nowhere little yellowish bananas will appear, then 3 days later the plant is full blown hermie essentially turning itself into a seed factory if you keep it alive. I think of them as typical females, some are real hot when they are young and get ugly but still think they are hot, some are ugly ducklings and turn into beauty queens, and they all are going to play games with us.
