I picked up some Flourish Comprehensive for the first time today, and when I started to unscrew the bottle, it made a kind of popping noise. Then when I took the lid off, I saw the seal was broken. I'm not sure if the popping noise was the seal breaking, or if it was already broken before I bought it. Does it seem too risky and I should return it to my LFS (a fairly long drive away), or is everything probably fine? The fertilizer also has a strong smell, not sure if that is normal.
