Mixing Nutes in 5 gallon and letting them sit??

Is it ok to do this?? Will the ph of the water change if it sat there for about a week? I'm using foxfarm nutes only.

I know the ph doesn't change cause I'm doing that right now but I was also curious as to how long you can let mixed up nutes sit. I mix a gallon at a time and it lasts about a month depending on age and strain of plant. I keep them in sealed bottles sterilized with bleach water and rinsed prior to filling.

As long as you shake them up every time you use them to get the nutes that have settled on the bottom back into solution, you'll be fine. If you were to let stuff sit around forever, the only problem I could see would possibly algae.

i do the same thing too...toss some airstones in there to keep that water from getting stagnant.

Thanks everyone. Will definately try the airstones. Never used them before
