When I first started growing I ordered the Advanced Nutrients line of products. I read a lot of good about using fulvic acid and bought AN's F1 ( Aunt Engy's ) Fulvic Acid. I only grew 1 or two plants at a time and that 1 Liter bottle lasted me about a year. The entire time it maintained a very clear and honey color.

Recently I was at a store that sold Organicare Fulvek Acid. Seeing how I was out of F1, I bought a liter of this brand. When I first used it, I noticed a slight layer of slime at the top that poured out in a clump at first. Didnt think too much of it as the rest seemed mostly clear. Well that slime kept coming back and a rotton smell started to be noticable. I opened the bottle today and it was all dark, almost green and very stinky like rotten eggs. I wasted a 6 gal batch of nutrient mix because of that. I tossd it all including the 80% full bottle of nasty Fulvek Acid.

Question ... is this normal for Fulvic acid or is this product / batch just bad?
