I agree… once you have an idea you dont need it really… i can likely ph correctly just adding the same amount as always typically… learning which nutes change ph helps alot too…
Once you have the fear of failure from failure… you will do anything to make it stop…
I had one time refused to even get one. Because years ago we used hard water I couldn’t ever get the pH correctly. And that’s when I found out you do not mix PH up and down together.
You’re not even supposed to store them next to each other… thats something that blew me away… that in a bottle they can affect each other anyways if close to each other
Those two chemicals definitely do not like to be mixed.
I can only speak to hydro nutes in coco or water culture
But being off .1 means deficiency in sensitive varieties with the nutes I’m using currently. Off .2 and there will be issues.
pH is not a linear scale, and .1 may not sound like much, but it can be. Accuracy of .01 means I can rely on it, even if it’s off a little. Not the case with lower resolution.
If you’re in soil, may not be a big deal as microbiology is doing work for you
From my experience its ph fluctuations that cause issues, not so much when its stable, where ever that ph number might be. Chasing specific numbers you’re aiming for can cause acid building up using PH down…in soil…I’m in Autopots now with a Promix type, peat based mix 60/40 ish. I don’t give an RA about my ph. it is what it is after adding nutes to water .There are not many full on hydro growers on the forums I’ve seen. Most use Coco and chase ph constantly creating more problems than its worth IMHO
Sounds like you understand your medium. That’s good. Peat moss has som pH stability, and likely what’s doing it for you.
I know coco. And it’s critical you keep pH on point. There’s no chasing pH. When I mix my res, it starts around 3.5ph (good luck watering with that). I add my silica, it rises to 6.0. in the morning it’s the 6.2 I need. They get that every time and are as happy as can be. Even w the added organics (I don’t do pure salts, better flavor w organics).
IMHO, you should stop making assumptions about others.
If it wasn’t for the water bill, I’d still be in Leca/hydroton. But I’m trying to compromise for Earth’s benefit.
I could post the nutrient a availability chart, but it may be wasted here
This is a sensitive gal.
Edit 2: failure can cause fear of failure true, but the fear is not conquered until one understands the reasons why.
Good morning @Hemp and OG!
Wow! This is the most drama I’ve ever seen on Hemp’s thread! Normally it’s a very chill spot to hang. lol
I’m sure as chill as he is, that’s the way he likes it. lol
No worries I’m done with this thread. And trying to help
Old man wisdom says just because you’ve been doing something for 30 years doesn’t mean you’ve been doing it right 
. Using strips is like turning an 11 mm bolt with a 7/16” socket — sure, it moves, but it’s sloppy. Some of us like to be on center. Strips = ballpark, meters = precision.
And why do you need precision when plants don’t? strips are accurate without the need to re calibrate. if the strips say your close to 6 what do you care if its 6.1 or 5.9 its close enough. I think you missed where I said fluctuations cause more issues than being a point or 2 off. No where I’ve read says you need exactly 6.5 or 5.8 or 5.6 where ever you ph to. FLUCTUATION …google it.
It is strictly preference.
They also have a shelf life.
I have to agree. When was going hydro at first it drove me crazy recalibrating mediocre pens. I dropped the doe on a blue lab and never turned back. Hell, I didn’t use it for a few years and it was just a few points off before re cal.
At the end of the day its the comfort of knowing that your ph is fine. If you have issues it’s elsewhere.
