Been having massive problems with vapes not hitting properly after a few hits.
After filling and immediately capping a very small air bubble gets stuck on the bottom of the cartridge. Once I start taking hits the air bubble makes its way over to the oil intake hole like the picture and heavily messed up airflow.
I stick the needle as deep as I can while filling at 120f viscosity but still does this on about 15-20% of carts.
I am using 91% distill with 10% terp and 5% viscosity
