I have just read through every scrap of information provided by the manufacturer (Monterey) of this specific product. It discusses dilution and frequency of application, but nowhere mentions application rate for specific uses. The only guidance might be the 4000 sq. ft. maximum coverage (for weekly? for monthly? application). If you assume 3.75 square feet per full-size tobacco plant, then you can calculate an application rate (how much of it to apply).
So I would say that it is probably safe (for soil drench, rather than foliar spray) for your tobacco, but unlikely to provide optimal fertilization.
