I am having a bit of trouble buying distilled water so I had to choose purified drinking water from the local grocery store. I am running in DWC. Is this ok I will meter the ec and ppm.
Grocery store purified water instead of distilled water.

Hi again. It should be fine, it will have a low ppm and ec and drinking water is usually a higher ph around 8-9.5. Try spring water if you can. You can look up ph by brand on youtube or they probably have spreadsheets online.
ok would you ph down to 7 first and let set then add nutrients? I am mixing silica in the mix. I am using AN PH perfect trio G/M/B plus additives from an.Thanks for your help
Im not sure, ive heard to only ph after you add everything and Ive heard to only worry about ph after adding silica. I think it depends on your nutrient line. Lets get someone to weigh in on this
@St. Tom
I think i am thinking too much lol , as usual. I know exactly what you are talking about with silica and I always add first, been there got the tshirt and hat from mixing wrong. I will add my mix then check ph and adjust,
Additives, main nutes, ph up/down.

ph and ajust after you've had everything, my friend
With you "using AN PH perfect trio G/M/B plus additives from an," you are not supposed to do any water or post mixing pH adjustment (involving adding salts), presuming you start with lower EC/salts/ppm water. The whole idea of pH Perfect is that you don't correct, don't add salts, that the nutrients remain bioavailable over a wide(r) range of pH in the medium/soil.
I'm rather sure AN never recommends pH adjustment with pH Perfect base nutrients (used with 'good' water). I suggest read your nutrient's and, as needed, other Advanced Nutrients instructions.

- What I got...
Like st tom said PH last and definitely check the PPM if this is a machine that fills the jugs at the store they can be good and bad depending on how often they are maintained (filters replaceed)
I have no experience with AN nutes but heard that it is not PH stable unless used at full strength when you start diluting the ph prefect goes out the window

I have not "heard" this. Some of the most popular nutrients not being dilutable? Obviously, not the case. And how would further diluting the nutes make the components less bioavailable?
Again, pH of the feed and ph stability are largely irrelevant. That is what pH Perfect does, why you use it. As long as you use low ppm/salts water and don't add a lot of salt supplements, e.g., load up on cal-mag, it remains in optimal pH range for uptake of its nutrient components.
There is a lot of anecdotal evidence supporting that lower than recommended doses of pH Perfect work rather well. I and apparently most pH Perfect base nute users, a good portion of AFN members, feed at ≥2 g/L (1/2 strength or more).
