New Grower Removing Chloramines From Water

I have no direct experience but, it would seem to me, that ph fluctuation in RO water would be more likely related to what you add to it than the water itself seeing that its ph is neutral. It would also be a matter of what you ph with. "Organic" ph control is only good for about 24hrs in hydro. Your nutes, what buffers they contain, etc all play a part.
Yes, when you produce RO water you remove most of the salts that it contains (they become concentrated in the effluent) so that you are basically just left with water and dissolved carbon dioxide (which in theory should give a pH somewhere around pH 5.7, but will depend a bit on how pure your water comes out). Added to that the pH of the water will be more difficult to measure, because it contains very few salts, and this tends to make pH electrodes give unstable readings (the result will probably drift around more than in a stronger solution). The latter effect might make the pH appear slightly more unstable than it really is. Also commercial buffers will tend to be less accurate for calibration because they tend to be made from more concentrated solutions. I would imagine that you are probably much better off making pH measurements of solutions after nutrients have been added.
On another note, ammonia is lost more readily from higher pH solutions (pH > 7.5?). It is also a nutrient for plants and should cause them no harm (ammonium sulphate is a fast acting N supplement). Considering the levels of other nutrients that might be present I doubt that a little residual ammonia from chloramine would make any difference.
Off topic, but really not, I'm old, but I'm not that old, and the idea of buying water never dawned on me until about 10 years ago
Was wondering why my food bill is astronomical and found it was mostly stuff to drink. I drink good British tea, decent coffee, organic milk and mostly water, sometimes juice or soda, and it's over half the food bill
I didn't even count beer and liquor. (those are filed under "emergency funds)
Seriously though, they never would have thought of putting this garbage in our water when I was a kid. We'd have strung them up
