Because the chart is a joke. So is the forum. It’s the same crap posted everywhere with the chart and zero guidance.
I want to see the genius who knows how to show everyone how to measure .75 grams of week 2 fertilizer for a liter. 
@TonyBaggaDonuts Bro, thats honestly about as easy as it can get… you pull your digital scale out sprinkle fertilizer in until it reads .75 then mix it in 1 liter of water. Maybe this sport isnt for you…
I’m sure everyone has a scale. It goes from tsp to grams from one week to another and every post I have seen on here just shows the same printout with no guidance. It’s a guessing game. Thanks for the sarcasm. It reminds me of the 20 years I served in the Navy.
Could probably say the same about anyone mixing just 1 liter nutrients
