If you want good nitrogen dude, just get some fish emulsion or seabird guano pellets.

BatGuano is good, but unlabeled bags would scare me. You can get some poisonous dust from batguano if it is processed unproperly.

Scent free ammonia..yes the household cleaning kind...about a shot glass per 3 cups of water will suffice for your nitrogen as well. But don't add this during flower...only veg.

Good luck.
