There are a couple of things causing the glowing and burning....first and foremost, the resistance is too low. Add one other coil to compensate.
The next thing is to make sure your kanthal is wrapped very tightly against the mesh.... I achieve this by putting an unbent paper-clip or blunt syringe needle in the roll while I wrap the coil....just be sure to pull it back out before you smoke it.
The connections to the leads are the next culprit for glowing leads.... make sure they are wrapped very tightly....a wire wrapping tool is useful for this or use a ferrule or small screw/nut on a terminal or a termnal block connector. These work to keep your connections solid. If you can move the wire on the leads after it is wrapped, it's not tighe enough....worst case scenario, tighten it up with a needle nose pliers bu gripping the wrapped wire on the leads and turning them tighter (patience is key, it will take 3 or 4 1/4 turns to get it good and tight). You'll also want to make sure your air hole is as close to the coil as you can make it. It helps to cool the exposed kanthal and makes it much harder to get to that burnt taste
In my experience, you also want to keep the coils as close to the bottom of the vapor chamber as possible and as close to each other as possible without them touching. This produces very consistent vapor and taste in my setup.
One more thing....burn a drop or 2 or juice on the wires going from the mesh to the leads when you put a new coil on. It breaks it in faster.
Every couple of days you will want to give another tightening to the wraps on the leads to make sure they are still tight.
I am able to run at about 2 ohms with a 2900 Mah 18650 AW battery with no burnt taste and no glowing if I have airflow.
Hope this helps you guys. Good luck
