Your experience of a handful of grows?
At most.
If you were so knowledgeable you'd know temperature does not affect pH.
It affects EC readings.
pH doesn't give a shit about temperature.
I don't recall making that claim and I don't care if it does or does not.
You're also someone growing in coco (from the pics I've seen on your profile) and yet you brew teas as your method of driving down your pH.
~Most of my plants are in organic soil. One plant is organic coco, 7 others in
the grow master are a salt grow/coco.

I'm using apples to make vinegar, is that what you are concerned about? Nothing will live in that.
Or is it the leaves that I am using to lower the pH of city water that is concerning? Pretty sure that won't kill me either, it's outside.
Let me know if it's something else please and thank you.
You do realize some proper pH down and pH up will cost you maybe $20 and not do that?
What is 'proper pH down' even made of and where does it come from? I usually use citric acid, vit c, epsom salts and vinegar also. I'd rather make my own for quality reasons and knowing where it comes from reasons.
I don't grow for profit.
At least ten, maybe a dozen threads you've responded to today are all "get the media pH to 5.8, you'll be good." Almost verbatim. That's not good advice man.
I grow and have grown many plant species, all I have to worry about is having them in the correct pH medium and they do great. Some food of course, but if pH is off, the food doesn't work. Happy roots, happy fruits and pH being good is
required. Any medium I grown cannabis in or have grown in, needs ~ 5.8 pH, according to any soil meter of any kind, I have ever had. I have grown dwc, coco, soil, organic soil, peat based, tree bark, maybe more.
MEDIA pH DON'T MEAN SHIT. SOIL PROBES ARE GARBAGE IN INERT MEDIA.
Every plant I have ever grown cares a lot about the medium being ~5.8pH
Not sure what you mean. How do you define inert media? All my soil probes work in every media, even tree bark.
Inputs are where it's at. If one wants a real confirmation of what's going on, a slurry test is the guaranteed, proven way of validating such, depending on media. This means, it only applies to peat and coco. Perlite, Hydroton, rocks, rockwool, pillow batting, etc it's irrelevant. Soil, coco and peat are the only medias a slurry test might mean something. Regardless, it's still a garbage metric if measured in the media.
Inputs will effect the medium itself, some more than others.
I have done slurry test, next to runoff test, next to soil probes, next to liquid pH probe pushed into the medium, they are all the ~same. Always use 5.7 water (prefer ~0ppm), and make sure you are within a couple points and you are good.
Even Bruce Bugbee uses runoff test, for pH and e.c. and says they should be within ~0.3 pH of optimum (~5.8). From everything I have seen, that is true but I don't like to go over 6.0. For e.c. he says 1.3 and about the same within ~0.3ec
I'll leave this up overnight, signing off now. When I log on tomorrow, you're going on ignore because I'm done with your kind thinking you know a thing because you've a couple grows under your belt and have money saving ideas. Either do the shit right or go back and play in the dirt. A couple harvests don't mean shit and it's people like you that make these methods seem more complicated than they are. Fuckin pricks.
Not even sure what you are trying to say but a lot of irrelevant stuff in your whole post about me that has nothing to do with anything, stick to the subject, unless you think it's me.
Can you show the science that says plants don't care about the pH that we measure with our medium/soil meters?
