CaliMagic directions say, “use 1 ml per liter (1 teaspoon per gallon)”. A teaspoon is 5ml though and a gallon is roughly 3.8 liters so shouldn’t a full dose of CaliMagic be more like 4ml per gallon?

I grow in coco using RO water and I feel like it’s pretty important to make sure I’m getting my nutrient ratios on point. I never thought much about it until I realized That CaliMagic is contributing the most to my EC, like half my EC is CaliMagic, not sure if that’s normal or not. I have tried contacting General Hydroponics multiple times and never get any response so I’m hoping someone here has some insight or am I over thinking this? Thanks in advance.
