microbial

About a week or two ago I mixed up some OG Tea microbial tea and some Flora Nova into a gallon and I didn't even use half of it. I put it away and thought I'd use it sooner but haven't, and now I'm out of the OG Tea. Wondering if anyone has used stuff they mixed a while ago and had any...

Or will it kill the microbial life? I'm talking full strength 1000-1400ppm.
