Shelf Life Of Foxfarm Nutes?

Hi,
I have the Foxfarm trio (Big Bloom, Grow Big, Tiger Bloom) which I purchase a couple of years ago and I've been using them for this year's grow. Does anyone know the shelf life of these liquid products? I emailed foxfarm but did not receive a reply. Thanks!

It's unlimited I am fairly certain. However, the whole trio is not organic, only Big Bloom is.

Once your Grow Big or Tiger Bloom begins to get cloudy its time to think about dumping them and getting fresh. The cloudiness is a sign the elements are beginning to precipitate into one another. Recent changes have been made by most nutrient companies including a expiration date either printed on the label or a sticker added to the bottle. Most liquid synthetic nutrients will precipitate over time.

The question is, why haven't you used them in 3 years? With that much money invested in fertilizer you should be growing all kinds of veggies and such, along with your buds. Companion gardening helps control pest problems.

How do you dump it? Just pouring it out on the yard contaminates ground water and isn't very smart or environmentally friendly. What's the proper method of disposing old fertilizer?

I'd sell it on craigslist for $10 then go buy something else.
