Hey guys! I'm totally new here but was hoping you could help me out. So I bought a smok stick v8 around 2 weeks ago, and suddenly in the last few days it tastes burnt for some reason. After one week it started tasting like cotton and happened randomly every few hits, RN it happens like 1 out of 3 times i hit it, and it tastes burnt now. I do use it a lot, i have refilled my tank around 12 times since i bought it. Do you guys think it's time to change the coil now? or could it be something else. Just some info to add, I have tried opening and closing the air flow vent, no difference at all tho. Thanks for reading and hope you can help!
