Hi guys. Math isn’t my strong suit but I am trying to figure this out. A bit too stoned for this so I would love a second opinion.
Let’s say a fertilizer brand is 20-20-20 and says to add 1 Tbsp per gallon of soil. Assuming the soil has no nutrients in it, what mathematical formula would I use to figure this out?
I am thinking if one tbsp has a 20-20-20 rating than once I dilute it 256 times (256 tbsp in a gallon) it comes out at 20 divided by 256 = .07
So my soil would have an npk of .07-.07-.07 right? Or am I way too stoned to try to be doing math right now?
