I agree with ProGro...that does seem to be a pretty heavy-duty fertilizer. While industrial strength fertilizers can produce plants with impressive sized buds, they can also permeate into the foliage/stems/even buds, and leave you with something that doesn't have a good taste and produces a high that kinda feels to have been induced chemically.

Bat guano can be used in conjunction with other organic fertilizers throughout vegetation and even into flowering. And, if administered correctly, is almost guaranteed to produce the best tasting (and smoking) organic buds in the end. Some might claim that you can't produce as large of a yield without using these heavier chemicals...but I disagree, and have seen organic grow methods produce some of the most amazing cannabis I've ever seen, and smoked.

Regardless, remember to flush your soil with just water at least once a month. And be sure that the pH of the water and soil is fairly neutral. Salts in many fertilizers can build up and actually prevent any nutrients from being absorbed by the roots. I would recommend not using any fertilizers, with the exception of just a select few, during the last 2-3 weeks of flowering...and be sure you remember to flush the soil regularly then. If you're just itching to add something to the water that could directly affect the final product, it should just be sugar or molasses. Trust me on that one.
