Thanks bro. It's interesting, I'm getting a better understanding of what the NPK ratio is.
But in your chart, I don't understand what the quantities of which powder you use to achieve this result in PPM.
For the 3 powders short/hybrid/long flowering, I think you need to choose just one, right?
I would like to be able to do my hydro grow with these 3 powders grow, hybrid, and booster pk.
