In the past month, I read a lot of new posts from growers having a pH problem, of the pH going from an adjusted 5.8 at night, just to spike back up to 7.0 by in the morning.
There were two common things I noticed. Half of them were using a nute-soup, or a mix of three to 6 different things in their water. They would have a VEG nute, or maybe two different VEG nutes, a catalyst like Liquid Karma, some Cal-mag supplement, some Hydrozome, some pH Down, some peroxide, etc, etc etc, and I could easily blame the pH spikes on the nute soup they had mixed.
BUT
I also noticed that over half were using R.O. water or Distilled Water. When I started researching pH, I read up on Buffers and Stabalizers, and the fact that water has to have something in it, like some minerals, or solids, to buffer or stabalize the pH or the pH will spike rapidly up and down.
I saw a couple of posts from Filthy Fletch about this, he's a knowledgable, experienced well-read grower. He seems to be really down on R.O. water or plain pure distilled water.
Does anyone know anything about R.O. water and Distilled water NOT being the best to use in Hydro because of pH problems?
Does anyone have any cut and paste articles or links to, or experience or some FACTS about R.O. water and Distilled water NOT being good for pH and Hydro growing?
Any info on Buffers for pH?
