Here is a cut and paste from Dr. Vondankenstien.......

As you may or may not know---soil PH should be between 6.0 and 7.0 for fast and healthy growth. That PH range will allow
for fast and complete assimilation of major/minor/and micro nutrients. The following is a rough guide that will allow you
to make sure your soil is in that PH range and if not, how to correct it. Most pro mix's are blended to be at 6.0 to 7.0 pH.
You will need the following to test the soil PH:

Soil
Cups
PH up +
PH down -
low ppm water
PH tester

First put the soil in the cups, Then you need to mix a water solution to 6.0 pH and another one to 7 pH. Calibrate your pH
pen or tester. The pour the 6.0 solution into the first cup of soil slowly and collect the run-off. Now pour the 7ph solution
into the second cup of soil and check the run-off. Now check the 6.0 run-off cup and if it's below 6.0 then we will need to
add some dolomite lime at the rate of 2 teaspoons per 4 liters/or gallons of soil. If the 6.0 run-off PH was above 6.0 then
we need to check the run-off of the 7.0 cup.

1.---If the run-off PH of the 7.0 cup is less than or equal to 7 and the 6.0ph run-off is greater than or equal to 6 you are
in the sweet spot and your soil is in the correct PH range.
2.---If the run-off of the 6.0 cup is less than 6.0 than you will need to add a little dolomite lime to raise the PH of your
soil.
3.---If the PH of the run-off of the 7.0 cup is over 7 than you will need to add more peat to your soil to lower the PH of
your soil.

now that was too much work for me so I used fox farm ocean forest and pearlite anf did not even check it.

good luck

soil ph is 6.2 .. 6 - 6.5 is safe anything higher is to alkaline, anything lower is too acidic .. getting up to 7 you will see deficiencies. Hydro is 5.8 safe range from 5.5 - 6
other statements are false

I doubt its even an issue, but unnatural acidic acid is apparently cancerous .. So vinegar with unnatural (added) acidic acid is apparently no good, these days whats not cancerous. I would use it anyways, I doubt the traits are carried through the plants and ingested, so you should be fine. 6.2 is best though

reeto i made sum ph 7 water up and give my a rinse threw as i wanted to freshen up a bit the run off for all plants was like ph 6.15, what does this mean?
4 weeks ago when i moved up pot sizes i mixd half dose ph6 guano in with soil ,npk 8/1/1, was this a mistake? will that small portion ov guano be the cause of my low ph runoff or wud it be used up by now?
also if i put ph7 in and got 6.15 run off does that mean i should use about ph6.9 for a bit cos if i go lower i mite end up wit runoffs around 5.8/9

any good info ?

peace ill av to put a pic ov my pride possesions on innit,, me g-bombs

Here is my suggestion, it probably won't be popular, but here it is. I would use the tap water you have and grow using it to see what kind of results you get. If your plants are growing fine then I'd stick with it. I like to keep things simple, if I get the results I want without having to mix a bunch of chemicals to match something that is supposed to be optimal, then I'm fine with it. It's not a perfect world and plants are adaptable. Some people are perfectionists and wouldn't think of doing it any other way than optimal, but I try to do things the easy way first and then go from there. I'm not trying to start a disagreement on what is better, everyone grows their own way and if you get the results you are after that is all that matters, I get the results I'm after with tap water, maybe I'm blessed with the perfect water, maybe not, it just works for me and I stick with it.

the only reason I disagree with you is that plants need a certain PH value at certain times in their lives so they can more readily uptake nutrients. It's possible that you just have a good balance that provides good nutrient uptake in all aspects of growing weed. (6-7 in soil). If you want to be sure though and get the maximum growth then you would want to be more stingy and test the soil PH and water ph, etc etc.
