Ixnay the guano, there are so many other amendments that do the same thing and aren't nearly as hot.
I used to use guano back when I followed Subcool's recipe. Not knocking the guy by any means, he's a great guy and I want it on record that I'm not trashing the guy.. it's just that he'll be the first to admit that he isn't knowledgeable with organics and has been quoted as having said something along the lines of "I don't know how or why this works, but this soil recipe works for me and I just thought I'd share".
The only amendments I use in my soil are neem, crab, and kelp meal and that's it. I simply cannot say enough good things about neem meal. Not only does it have great NPK ratios for veg, but the integrated pest management it brings to the table is worth adding it to any soil mix all by itself. Not only that, but when you have spare neem meal that you aren't using anymore you can easily turn it into a spray that will work just the same as neem oil. Neem meal is pretty much just the remains from when they turn the neem into neem oil, rather than throw the remains away it's packaged as neem meal. That's why when you make a neem solution with neem seed meal you need more of it than the neem oil, because much like cannabis oil the neem oil is much more concentrated.
I know it sucks that you have leftover bat guano, but I can't recommend switching to neem meal enough, even if it does mean you have leftover guano. I stopped using guano a few years back in favor of neem meal and haven't looked back.
