No i dont have one. I just use Chucks calculator thing. I add what that says should give me 20ppm, taking into account the Potassium that gets added from adding the KNO3.
Thats the only thing i cant calculate. From what i've read, people gradually upped their potassium levels until the green water went away. Then they knew what amount would lead to the perfect balance of nutrients.
But there's so many theories regarding green water that i dont think anyone knows much about it.
