Maybe you guys can help I vape 70 VG 30 pg juice and use I believe the 0.7 nautilius coils with a aspire tank and been noticing some leakage and spitfire but have my wattage set around 10.3 and 11.3. Never had a problem before but is it possible that I bought two bad 5 pack coils and that's the reason for the leaking and suture before that I never really seemed to have a problem?
