I've always sweetened my 30ml bottles with a 1/32 scoop of EM crystals from TFA. I want to start premixing the EM in PG and then adding it to my mixes. I've already figured out how to mix the 10% EM crystals with my PG, but am not sure how much of it would equal my normal scoop of EM. I was thinking 2-3%, but would like to get a second opinion first.
