Im making my own e-liquids for 1 year now and just now i got an issue, the e liguid i maded is hurting my troath, the mix is 100 vg base and it goes like this : 8 ml vg base 1.5ml flavorng ( the flavour is in pg ) and 1.5 ml distilated water. I bought 500 ml vg juice base so i hope that not the base is bad. The flavour is is good becouse i used it before and the water i distilated it with my expresso machine. I alternated the juices and the last badge is good and the current one is like burning or hurting in some way my troath. Any idea what i did wrong this time or what could be the problem ?
