Hey guys, my faithful 1.4 ohm coil magma has recently only been producing air filled, weak vape, throat scratching pulls. I always fire it for a few seconds with the top off to see what kind of vapor is being produced, and it looks the same as always from that perspective. Actually vaping it is another story. I've tried the airflow rings in all positions, along with several different juices and different voltages but I can't get it back to where it once was. I hate this thing right now! Help!
