Ok folks, I made a major change to the calculator, using tabs I made it easier to expand and add more products.
The "Adds" tab will let you enter the amounts of the products you want to use.
The "Results" tab will display the PPM calculations, chart and ratios as well as provide a mix calculator where you can input the gallons to multiply out your additions.
The "Products" tab is where we store all the product data
The "Tools" tab has the calculator for adding new products into the "Products" tab.
The "Matrix" tab is where most of the math happens, no need to mess with it, but cool to look at when you are stoned lol.
I didn't provide the EC calculations in it yet, just elemental PPM.
Let me know what you all think. Still needs to be made to look pretty but it's so much easier to expand and add new products as the formulas simply "fill down" meaning much less opportunity for error.
