premix nutrient solution

[DNLgreen]

Can I pre-mix a nutrient solution if I have an air bubbler running into the solution from the time I makes it to the time I use it ? I'm using the General hydroponics trio with Cali mag and growing in coco

my understanding is that the pump will continue too dissolve oxygen into the mixed solution rising the ph, maybe check the ph before using to make sure it doesnt change much
