Sorry to break it to you massbud but that's a male plant...... You did do a good job growing it but unfortunately this plant isn't going to give you any buds...... You can either scrap it now or keep it growing until the seeds come out of it. Chances are that the powder on the leaves is pollen...... Thats what I'm getting from your pics......anyone else??

Just to be sure, can you post a close up pic of the pollen sacks?
