Question about Bottle Nutes Shelf Life , how long after opening bottle?

[ROSTERMAN]

OK I have a lot of left over open nutes , General Hydroponics Flora series most of it and was wondering how long after opening
did anyone still use it? I have 3-4 yr old Flora series left in gallon bottles that I used this year to grow. So far the Plants seem fine and where they would normally be at this stage of the grow for me.

Normally if kept in proper conditions liquid ferts can last up to 10yrs.

I've often wondered. I now use Advanced Nutrients, but have the 3 part GH stuff, 2 jar Nukeheads nutrients mostly unused. Guess I could gift them to my other grow buds.

But is that for a sealed not broken unused?

Thats the shelf life during use if properly stored.
