that sounds like a bunch of nitrogen to me for cannibas! I am no expert by any means when it comes to ferts, but I use Fox Farms ( a highly recommended brand etc) and it's 6-4-4 If you want to see plants grown with it look here at my post:

I may be wrong and please someone correct me if I am, but I think that it should be a bit more balanced. Yes more N for vegetative growth but I would suspect that you would be giving it too much N. As I have said I am not sure but I do know that nute and ph problems is the leading cause to these "help what's wrong with my plants" posts. I was one of them long ago
Fox Farms also has micro nutes. I would say just ask around and maybe try getting a brand that you know is recommended and that works. FF isn't too expensive and be found at your local hydro shop.
Good luck,
