Looking at your photo, your coils seem to be heating unevenly and your cotton is definitely burned. Maybe you should lower your temperature, lower your pre-heat power, lower your watts. Also make sure that your mod is in the right profile (1-8) as the profile in eScribe, that you made your settings; it is a mistake that I once made. Also lock your atomizer's resistance with Escribe's resistance reading (not a seprerate ohm meter). Lastly look at the "real time analyser" when you vape, and fine-tune your settings.
