I got these numbers from one of the best selling products at my local hydroponic/garden store (no not miracle grow). Yes, I'm talking about hydroponic use, soil use, or any other medium like rock-wool.. I understand that many plants have a custom preference. I want this to be a custom blend similar to the products found in a hydroponic store (general hydroponics, botanicare, advanced nutrients)
