PH'd Nutrients drift while on shelf

Nutrients

I pre-mixed my nutrients and when I went to use it 4 days later the PH was acidic. Is it necessary to mix fresh every time?

Good ? I am not sure I only mix up what I need and use it…
@bob31 or @Donaldj might know.

Sorry this is the best I can do for you.

The chemicals in your nutrient mix will interact with each other a fact all hydro growers know all too well this usually happens slower with plants consuming and buffering as well from medium but nutrients come in separate bottles for a reason :wink: You can premix but ph adjusting should be closer to time of use

Thank you for the advice

Great thank you for the advice

I only mix what I need @EnthusiasticGrower because of the pH

Ill mix and let stand over night occasionally but only ph at the time of use
