Unless that's some kind of compost tea I don't think there's any point still mixing it after it's mixed.
I mix my nutes up in a 10L bottle and they can sit for up to and sometimes over a week before used up. Bottle just sits in the cupboard.
Is it okay to mix nutrients? I’m using roots organic so off the feeding schedule can I mix my Buddha grow with amino-aid, trinity, surge, and etc. I have the whole line up almost. Also I have this stuff called recharge I was wondering if I could mix that in as well in a gallon container
