I tried now with more cotton and it looks a little better but still in 1 hour i got literary zero bubbles and now im tasting cotton more than anything lol.. Idk anymore. Will keep trying and if i nail it i will let you know.
That is a new coil & 6 wraps not 7....
personally me thinks it is your cotton/wicking technique
either your cotton is shit or fake Muji or grain wanked
not fluffing ends and stuffing not tucking/placing them into wick channels
if your cotton was smidge too tight or too loose you should still draw bubbles
so the fact the bubbles are not appearing indicates the cotton is not drawing juice
It "should" vaporise and if cotton was drawing correctly it would replenish the wick
& bubbles appear no matter what I would have thought
I'm now almost starting to grasp at straws now.....
But I'm wondering if there is some of weird mofo vacuum or something
that impedes the gravity or air increasing as juice is drawn creating bubble etc....
This sounds fucking stupid I know but like I said I'm grasping at straws
coz something ain't right - you draw off vapour, juice gets replenished
air replaces juice drawn & little bubble forms etc.....
However if there is some weird alien twighlight zone vacuum
then gravity/syphoning bollocks could be impeded perhaps ???
I fucking doubt it unless tank is iffy (ish)
BUT it "might" be worth remove lid as you do for filling
then tanks a few draws (gently as it may flood and you get a mouthful of juice)
But take a few draws lid off and see if bubbles appear
I know there can't be a vacuum if afc ring is open as such
but I am running out of anything else to suggest before you launch it down the garden
