Shelf Life of Tropica Plant Nutrition (TMG)?

I use approximately 2.5 Liters of Flourish per year, so I buy the 2L bottles. It seems to darken by the time I get to the bottom of the jug, possibly degraded.

I did try TMG right after the name switch, and sort of want to give it a go again, now that I only have about 11 weeks worth of Flourish left. Unfortunately, as you know TPN/TMG now comes in gigantic 5L jugs, which would last me a pretty long time. Purchasing it by the half liter is just out of the question, financially speaking.

Is it wise or unwise to "stock up" in such a way on the TMG? I'm concerned that half way through it'll be degraded. With the sale at Big Al's coming to a close now would be the time to buy. Otherwise I suppose I'll just wait a bit longer and restock with Flourish.

I know that some folks 'swear by' TMG and have better results with it. I can't say that I've really noticed a big difference, but my growing skills were in their infancy at the time I tried it.

Well, update, I still haven't found any verifiable shelf life information other than someone on an old school newsgroup posting that 'Mr. Tropica' said it would last three years unopened or at least a year opened. Well, I decided to just not bother with it. It's such a shame there's nothing in between half a lifter and five liters... it'd be like buying pints of milk or gallons. You're losing one way or the other. I like that 2 quart size, heh!
