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?
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 You can premix but ph adjusting should be closer to time of use
Thank you for the advice
Great thank you for the advice
Ill mix and let stand over night occasionally but only ph at the time of use
I appreciate your advice thanks
