This is a common problem and usually caused by a flooded atomizer and/or a low-powered battery or a battery that is running low on power.
Bear in mind too that most e-cigs generally require a lighter draw than a traditional cigarette.
See also our article about e-cig tank flooded which will give you a lot more detail about how the liquid ends up in your mouth if it can't turn into vapour fast enough.
In the meantime you will need to clear your atomizer/tank of excess e-liquid:
If you’re using a sub ohm tank and coils and you’re getting liquid in the mouth, this example of what not to do with the likes of the Eleaf Melo, as an example, should prove helpful.
Firstly, ensure the power (ie the wattage or the voltage) is in the correct range for your coil.
In the case of the Melo 0.5 ohm coils it’s probably circa 24-26W. The Melo is designed to match the Eleaf iStick 30 mod which has a range of 5-30W but if you set the wattage too low the liquid cannot vapourize, and instead it will gurgle away, perhaps get darker in colour, and you’ll end up with it in your mouth as it has nowhere else to go every time you press the fire button.
You also need to use a good quality e-liquid with more VG than PG (VG is thicker than PG and produces a lot more vapour). An 80/20 VG/PG ratio is often ideal but you may find 70/30 is the right choice for your device.
Be aware that 6mg (0.6%) nicotine is probably an absolute maximum strength e-liquid to use in any sub ohm device.
If you can’t take the hit from the increased vapour from the VG content of the e-liquid, turning the power down will cause more problems than it solves, instead you need to reduce the nicotine strength, for example 3mg.
In addition to this, when you press the fire button you need to inhale directly into the lungs (“lung it”). Sub ohm vaping, which usually has a looser more airy draw, is designed for direct lung inhale, as opposed to the more traditional mouth to lung inhale.
