New Feeding Calculator Prototype

[Greenleaf Nutrients]

I'm sorry for my confusion and thank you for your fast answer. So 177 would be my base and then I want to start my first feeding at 300 I would just add 128ppm to the 177 ppm = 300.

Then when I want to increase my mega crop to feeding 500. Take that same 177ppm and add 323ppm for 500ppm.
and so on or am I off. If I'm off can you just put it another way thank you.

you are confusing this really hard.

All you do is add your target MC ppm to your base tap water ppm. Thats it, nothing else!
