Expired nutrients

it probably didn't do anything useful anyway. selling hopes and prayers in a bottle too often.

Hello. I just add some sugar like Bud Candy by Advanced or Karbo-Boost by Green Planet to give to little microbes a boost and prolong their life. They love sugar. Chuck.

Dont worry about it, its a mix of i dont know the word in english, sort of bacteria. If its expired they dead and it wont be that useful, but wont harm your plants just use it. It doesnt go bad like other mixtures. Well probably it can but you would smell it or something and that would be some extra mold not from the ingredient itself.

Once you've kept in reasonable temp You'll get another few months out of it. Think under 25c if I remember correctly
