Natural Nitrogen/Bug problem

Whatsup guys, im on my first grow. It was kinda just a spur of the moment type thing, so it got started a little late in the season. My little baby is a bagseed that stands a proud 14-15 in. high, and is starting to show signs of being a female. The little hares sticking out of the nodes are indicators of being female arent they? I have her in direct lovely sunlight growing in a mint garden. Well not growing with the mint just in its own pot amognst the mint plants. It is in some very nice miracle grow soil and is given a couple shots over bloom booster diluted with water about every 7 days.

Are there any vegetables or fruits that produce natural nitrogen?

And are those little rolli pollie bugs bad for the plant, if so what is the cure for it?

Thanx in advance for whoever responds!
