70/30 water recipe conversion to five gallons

Can someone just check my idiot-level mathematics here? I'm slightly losing it.
I'm trying to work out how to make the 70/30 water directly into five gallons of distilled, rather than by making concentrates.

The recipe says to make two 1000ml concentrate bottles with 14g of sodium bicarbonate in one, and 12g of magnesium sulphate in the other.
Then take 5ml from each to add to 1000ml of fresh distilled water.

So that's 0.5% of the concentrates going into the main mix. Which means 0.07g of bicarbonate and 0.06g of magnesium.

Five US gallons is 18,927ml, which is therefore 18.927x more than 1000ml.

0.07g x 18.927 = 1.32g
0.06g x 18.927 = 1.14g

So, if I just put 1.32g of bicarbonate (I'm going to try potassium since that is what I have) and 1.14g of magnesium sulfate in five gallons of distilled water, does that work out correctly?
