Some of the myco will lose potency over time. Myco effect is subtle. Differences between new and year-old nutrient aren't distinquishable to the eye.
The oldest nutrient we've used was 2 years, with the same results.
One caveat: this nutrient likes to be room temp or slightly above. If it gets cold and/or sits for long periods there will be some sediment. Put the bottle in a warm water bath or hot greenhouse to 90 degrees and shake for several minutes and it will come back and be perfectly usable.
All that said, we always prefer fresh, and recommend only buying enough nutrient for each season. We make fresh tanks every week, and keep next to no inventory. It's all bottled on the spot. When big orders come in, it's a mad house.
Best regards.....
