I have down to earths bloom 4-8-4 nutrients I boug...

Dry nutes can last decades. Does it have any discoloration? Signs of mold or bacterial growth? If not, it is fine. I buy dry nutes. they sit around for 2-3 years before i finish a 25lbs bag of any 1 product. does this have organic ingredients or ingredients that can rot? That would be a reason to throw it out, too. Looks like this is that type.. shorter shelf life stuff. Contact manufacturer, but they will obviously err on telling you to throw it out in hopes of buying another. Check bag for experiation date...or best by date... if stored in cool/dry place that'll last longer too. Maybe, try it out on some outdoor plants?

Im using advanced iguana juice grow that must be 5yrs right now.Ib bought some new iguana bloom juice to mix 50/50 with the old stuff just incase. Dry nutes last a lot longer but they say a lot about it is how its stored. It doesn't want to get too hot or too cold but I guess it doesnt matter with dry.Most liquid only has a shelf life of 2yrs,I guess this is why they dont put a date on the bottle. I buy 5ltrs and it may take me 2yrs to get through it but Iv never had an issue.

Should be fine as long there was no moisture in there.

If it has not gotten wet it should be fine. Maybe it lost a bit of freshness but its going to be broken down anyways to feed the plants. I'd still use it. no questions asked.

No mold, no shrooms. Why not? :-) Some people even ripen their soil. Should be fine. If you want to be sure, just put in a pot and test the runoff. 💪 Worst case you have to "dilute" your soil :-)

It is probably fine. The only issue would be any microbes that were in there may be dormant nut they should come back just fine. I would use it and see what happens and if theres amy negative effects then scrap it. Good organic nutrients are always valuable. My roots organics has a best by date on it and they still work the same even after the date. my local store will put discounts on them sometimes but i havent noticed any differences between an old bag and a new bag
