Hey guys i bought some of this stuff from the US. The container suggests 1 scoop per 10 gallon of water. That's really broad. On the next section it says 1 scoop is 1 teaspoon. How much of a teaspoon do I need to use for a 12L reservoir? Can a little too much of this stuff kill my plants?
Any help would be greatly appreciated.
