I just got a big jug of liquid karma from a friend theres about a quarter gone and he said its a few years old maybe more, I would like to use it so I was just wondering if it can go bad or if its safe to use?

no I tried to look it up on the internet but came up empty handed, and I looked all over the jug and cant find an expiration date, maybe I'll call my local grow shop and see if they know.

my former food-service experience says - when it doubt, throw it out.

but that may not apply here...

Thanks for looking, it seems that if there was an expiration date that we would have found something, I also had the guy at the store go look at a brand new jug in case my exp. date wore off my jug and he said that there wasn't an exp. date on any of them.

I was going to throw it out too but when I saw the price tag on it said $135.00 I gave it a second thought

yea..the best way to check organic ferts is to smell em when you first buy them...then in like 6-12 months if you still have same bottel smell that...if the smell has changed it is now degenerating...peace az

I used to have a little jug of liquid karma and it definitely smells the same, but I'm not confident enough in my smelling skills to determine if its old or not...
