Sometimes a vape that I love just doesn't work for me at times for whatever reason. I can tell within a few vapes if I need to switch to a different flavor so I don't waste juice when I'm not vibing with it.
Last time I vaped Admiral's Pipe from RBFS, a NET I really like, I found it pretty meh. I thought maybe it was passed it's steeping prime, but just dripped some now and it's slammin'. The chocolatey note is especially tasty right now.
Or simply a missed batch
