sledgehammer

This is my Forum post EVER!! I've always sought out Forums when i've needed information throughout my life....But this is my FIRST forum post EVER.....Better late than never....Greetings Community...Help me medicate the masses please. Finally moved to a legal state and I can live my dream...

My bottle of Sledgehammer (foxfarm) smells different than it did last month, I'm not terribly sure what smell it's supposed to have but it doesn't smell great. Is this common, or should i get a new bottle?
