I use TA blend in PG. Says on website, PA, 2 drops in 10ml of PG + some EM. Are they assuming 20 drops per ml or is it 40 drops per ml at 20 drops per ml the solution would be 1% TA, at 40 drops per ml the solution would be 1/2 %. Second Question, Have TA Diluted 50%, haven't used yet but would like to dilute further to the TA blend percentage, I would be diluting in PG, how many drops in how much PG to equal the TA blend mix??? Without knowing the strength of original TA ( 100% or 50%) used to make TA Blend. Thanks for help.
