Ph'ing my water correctly?

[8182KSKUSH]

what happens if you adjust your ph first then add nutes? I had heard that it takes more ph down/ after you add nutes to make an adjustment? Will phing the water first contribute to ph fluctuating in hydro/dwc?
Again, nutes first, adj ph after right! Is that true for soil and hydro?

If it's taking more pH down to adjust nutes AFTER adding ferts as compared to BEFORE, you see how it would logically be easy to make mistakes?

Mix up your whole feeding first, then bring it to the proper pH. Do this all immediately before use.

In hydro, fill your res including all nutes and supplements, then test and adjust the pH.

I've been using the aquarium test kits (test tube - color indicator chart) for many years, and I do adjust my water first to 6.9 to 7.0, then add nutes.
I'm on a fixed income, tho...and can not justify buying a new ph probe, when I have been able to live without one for many years.

Is this optimal...no.

It might just be, Rusty!

After spending $20 on a cheapo meter, $25 on another meter, and finally $35 on a electronic probe.....

I had to buy the $7 liquid test because all of the above is bullshit.

I finally was able to afford a $60.00 ph pen and calibration solution. Have compared it to the aquarium tests I've used for years, and they are only about .1 off from each other. (close enough)

Soooo...

I use GH ph down, and mix the water to exactly 7.0. I then add my Fox Farm flower nutes. (Big Bloom, Tiger Bloom) at 2 tsp/gal each. According to the ph pen, the ph drops to 6.3. Tried to use the aquarium kit, and color from the nutes was messed-up enough (cloudy) to not be able to really tell.
As the aquarium kit does great for clear water, will still use it to double-check my pen and for a back-up.
Was amazed that the ph would drop so much, just adding nutes to the water.

Can someone post a link to a good ph pen? ebay?

[Rusty Trichome]

Got mine from here:
Discount Hydroponics - Waterproof Testing Pens

and that wont test my soil's ph right? is it really neccesary to buy an ec and tds meter also?

I have nothing against the liquid testers.....the pen is merely for convenience. And when you check ph, ppms etc on several different solutions several times a day.....convenience becomes a big thing.

PS....Always ph last.....daily.....hourly.....it changes in the blink of an eye.
