From what Ive read...does a burnt taste mean the carto is ruined? What am I doing wrong to cause this after 3 light days of vaping? I boiled them for 4 minutes the 2nd day just to clean the overpowering 24 mg nic out of them.o I added Humco VG (1/2) to lower strength, too. But, they seemed waterlogged after that and taste changed to burnt....yes I blew and blew -even after 7 hrs of sitting out to dry. Have I ruined them? Plus Im not getting 3 ml in these things...they are Leo cartos - not the LRs. I think Ive ruined them. Ive been using regular carts/attys because they taste better -not great but better- and from all Ive read...that isnt right. Cartos are supposed to be better tasting right? Ive ordered LRs -my supplier didnt have them but it will be a few days til I get them. Dont wont to start smoking again...Any suggestions? Should I boil them again????
