this thread just saved my ass. i was just about to pour 1 yr old grow big on my babies. it has been sitting out on the porch but i am 100% sure that temps got higher than 80 degrees.
Does this apply to Earth Juice? I had mine (grow & bloom) in the kitchen for about the last 10 months, it was in the 80s during the summer but not often. 50's the rest of the time. I thought I could get away with using the bottles again.
I've used older EJ before and not had a problem. I'm skeptical that it could turn into something toxic to plants.
