My PH Mistke and Correction

[Flockshot]

I am new to GH Trio and I think I learned a lesson last night:

The Story: I mixed my nutrients just right. I then adjusted my PH to 6.0. About 15 minutes later, I watered my seedlings and was getting 5.7 to 5.8 runoff from every plant.
I tested the feed water and sure enough it was at 5.8.

The Correction: When using GH Trio it is wise to mix your nutrients early (maybe even the day before) and put in your bubbler stones. This allows the buffers in the GH to adjust the PH over time.
Then when you are ready to water your plants, just adjust the PH and water away.

My 2c.

Awesome tip bro.
I'm using GO, so I assume a similar principle applies.

My question would be, is it safe/advisable to mix up your nute feed a day in advance of feeding?
Funnily enough I mixed up my GO nutes today with some added calcium, epsom salts and silica (Dyna Gro Pro-Tekt), but didn't have enough time to water all my girls. So most of my nute feed is sitting until tomorrow when i'll be able to feed them. I was kinda paranoid about leaving it sit for a full day before feeding.

I used GO for my last grow but never mixed that far in advance. My assumption would be that if you put a air stone in it you would probably be ok. HOWEVER, I really do not know.
