I don't think there are any drop in
smok coils for temp control, so yes, use wattage only. I stand ready to be corrected.
Some wires like titanium and nickel can ONLY be vaped in TC but it's a safe bet you are using kanthal.
I often screw in my
tanks too tight, but an alan wrench in the airhole (you need it really seated um, fully like it won't move) for reverse leverage usually steers me right, and if you can get the top of the
tank off, addressing the bottom part will be easier as you won't have the glass to deal with. It's a thought anyway. I always want to tell me "Anna, finger tight is fine" but I often ignore me.
Welcome to ECF.
I have not heard ANY smok complaints recently now I think about it,
