Simple NPK Calculator

Good app but would be better if you can enter your own NPK % in the source field. I make my own NPK and my nitrogen source is 8% you can not enter this amount anywhere only pre made entries. Can it be fixed to allow the user to enter the % of the NPK source. That way it will be accurate and can enter any % of the source nutrient you want to add.

If you choose to make 100kg of a desired formula selecting the nutrients gives you 120kg. It should be improved. Thanks.

I wish I get more than 5 star its great if it calculates real amaunt developer need to add more salts like potassium nitrates etc to best performance I am exactly searching software like that thank you so much
