3-4 days is way to early too tell. Give it about 10 days. If you see clusters of these balls at each node where the new growth is taking place, then it is a male. There will be 3-5 balls visible at first. Trust me, my first female looked like it had those balls for about 3 days, and I was going to kill it. Then one day some VERY tiny pistils came out.

Growing plants take patients. Just wait another week and know for sure. You will be much happier in the end if it turns out female. If it's male, then you will be able to tell for sure next time you grow.
