Regardless of the reason, what happened to you is not normal at all. Most dj fans will hate this suggestion, but right now on seedbay there are packs of blueberry f2 and a few other lines from dj's gear for like $25 a pack. Cheap enough for a 2nd shot to maybe change your opinion. Fractal also has packs of f2's from old dj bb stock on sbay for $50, if you wanted older stock. They're a few years old though.
