put some more cotton you clearly have a little flood (liquid penetrates inside the chamber) and when you blow into it the liquid leaks. this flood should not happen if you put the right amount of cotton (don't put too much otherwise you'll have dry hits)

you need some more days to master this atty, I had similar problems but now this thing vapes flawessly, even if I let it stay filled and unused for some days, no leaks from the air holes

hope it helps
