The right ingredients are there, but the relative amounts are way off. Typically we dose about 4 times more nitrate than phosphate, but this mix has about 1.5 x as much nitrate as phosphate. We dose much more potassium than phosphate, but this mixture has about the same percentage of both. You might be able to use this as a substitute for KH2PO4, our usual source of phosphate, but that's about all. This mix contains a lot of ammonium, the "good" form of ammonia, so that is probably not a problem. You might be able to "balance" the nutrients by also dosing K2SO4 for more potassium, if you want to play around with it.

As Hoppy already said, proportions for macros are way off: too much phosphate and too little potassium. Ammonium Nitrate is a bad form of nitrogen for tank - bad for fish health, good for algae. Proportions of micros are also very wrong, for example, it has just 4 times more Fe than Cu (70:1 in CSM+B), 2.5 times more Cu than B etc.
