HELP! quick ?

My FF nutes go by tsp/gal, but I hardly use half a gallon when watering all of my plants....I jsut have a jug labled TigerBloom, that I mix and keep. I smelled it, and it smells like the water in it is going stagnant or something is rotting...

1.Should I be only mixing right before feeding?

2. I went ahead and watered my girls with this, DID I FUCK UP?

I mix my nutes 2 gals at a time, it takes 6 feedings ( 3 days ) before I use it all, seems ok to me. 'course I don't smell mine.

yeha haha I really dont know where the urge to take a whiff came from

Do you smell your finger after you scratch your balls? LOL. Seriously, don't worry about it except you should shake the hell out of it before use to oxygenate it. (the solution , not your nuts)
