I'm using Aspire Nautilus Mini.
Since I had couple of issues with juice coming out of the drip tip, I sometimes use some paper and clean the drip tip and the airflow just to be sure.
I've noticed that there is some black ash or curd inside the coil. Is this coming from wick, coil or is it burned e juice? Is this normal? I don't get any burnt taste but is there any danger to inhale this black ash?
I've already checked both my Nautilus mini and the coils and they are authentic aspire products.
Thank you in advance for your answer.
