I ordered some 100 mg 25/75 pg/vg e-liquid and when it got here the bottle was a little wet. I noticed the cap was not on all too well, it doesn't look like too much leaked out, but I'm wondering if it was a little exposed and went through some harsh conditions like being too hot if the liquid might have gone bad. This is my first time ordering nicotine for DIY and it smells pretty bad. Is it supposed to be odorless? Thanks.
