Does it contain other trace elements such as calcium and magnesium in addition to NPK？

it has very very small amount, I suggest getting a bottle of calmag. Keep in mind the cal mag has N in it, so use the grow formula as directed, but every other week substitute the same amount and use the cal mag in its place. Notice this product in part of a 3 part system, you need at least all 3 bottles if this is all your using,

Would this work in a Tower Garden instead of the nutrients in comes with? This looks like it might be better quality?

I don’t have a tower garden. The quality of the product is amazing. I recommend trying it

how many gallons of nutrients will this item produce after adding water? thanks.

The container is 32 oz., for recirculating systems it is 2 tsp per, gallon, for heavy feeding 3 tsp per gallon, and for supplemental foliar 1/2 tsp per gallon.....so a lot.
