Bat guano

So I have a few simple questions about using guano.
being that I am doing gureilla grow feeding is going to be hard so I was looking to mix bat guano with my soil and have it feed my plants through the season but before I just go mixing I need some guidance.

from what I understand there are different guano based on location. So choosing one high in nitrogen would be for veg would probably be a safe bet but will it screw up my grow if budding starts and there is too much nitrogen in the soil or should the guanos nutrients be exhausted?

Do I use it in a top soil and dig I out and replace it when it comes time for budding?

What's the surrounding vegetation look like? Thin and scrawny or big and lush? That tells you a lot about the state of the native soil. If you live in a good area, you may not need to feed much or amend the soil, but you can always take a sample down to your local Ag ext. and have it checked. Not a good idea if you don't know anything about gardening, soil, or plant nutrition. They sell NPK test kits at Home Depot and Lowes, that will give you an idea of what, if anything, the local native soil may be lacking. But to answer the question, I'd hold off on the guano and use it as a topdressing when you are able to visit them. Every couple weeks topdress some in around under the plant in an area as wide as the lower leaves cover. Higher N during veg, then start with a high P guano after you start seeing budding. It will leach in as it rains. It would be better if you have enough time to sit there and "scratch" it into the top couple inches, but just dusting on the surface will work well.
