Hi just wondering do you need to ph distilled water after you add organic nutrients like BMO? of will it be around 6.5 ph automatically?
DO you need to ph distilled water?

yes..you want to check the ph of everything you feed or water your plant...disstiled water only means it doesnt have the chlorine or other impurities of tap water...different disstilled waters have different ph levels...

thats very true but the ph generally stays between 6 and 7 in the different distilled waters.

nickfury510 and Tryingtomastrkush are both correct. If you are adding nutes to the distilled water, that's when it's really important to check the PH. Different nutes will change your PH after they are added to the water, usually lowering it, so that's when you should check it. If you're just watering with distilled water and NO nutes, you don't have to be too concerned about the PH being off.

In soil........in hydro you would need the PH a little lower than you would in soil......so if you are growing in soil and just watering them its not a huge deal to not check the ph of dsitillled but if its hydro you need to make sure it is the proper ph no matter what

Yes, this is true. I'm strictly soil, so for soil grows it should be good, hydro you would need to lower it. He wants his PH around 6.5, so I assumed he's soil too.

yeah man i assumed he was soil as well i just thought i would clarify so no one gets the wrong idea from correct information, ya know?

When we measure PH, we're mostly measuring how much acid is in the solution.
Other factors can affect the PH, but the thing is with low ppm solution, it takes very little acid to affect the PH.
In Distilled/RO/DI water, even the amount of dissolved CO2 in the water has a profound effect. This is because the ph of the solution is a product of the ph of all of everything that's in the solution.
If you take some say ph 7.0 distilled water and add a tiny little drop of PH down, it's going to take it very quickly to a much lower PH.
Now if you pour this into soil, everything that the water mixes with on the way through is going to have a much more significant impact on the actual ph of the water.
If you ph adjust RO water for say, clones. It will likely drift very quickly. However, if you add some nutrient - ussually Cal-Mag, even in a low concentration (around 200ppm), it will buffer the ph and it will be far easier to maintain the desired level.
We always adjust ph after adding everything that will be in the solution when applied. This way, we add enough acid or base to offset the acid or base in the solution.
In Hydro, as plants use nutrients, this relationship changes, as does the ph.
In soil, you can overflood plants and check run-off water to determine if you should use a higher ph or a lower ph to get the soil into an acceptible range.
But yes, you should always check ph of any solution before administering to a plant.

I just checked the ppm of my distilled water and its an incredibly low 000 ppm!!!
