Do you check ph in soil?

Australia water lol
generally they keep tap water alkaline, so its not corrosive on pumps and lines, bar the small amount of calcium and magnesium scale, i.e calcium carbonate, magnesium hydroxide, calcium sulfate, the stuff that leaves solids on your silver taps and stainless steel sinks thats hard to remove.

@Renfro Yes.. this is a tool everyone needs!. He helped me out when I was at my wits end when I could not figure out what was going on with my plants early on. I have the Apera PH8500 with spear probe. Had a little trouble with the first 2 through Amazon, but bought the 3rd through Apera direct and this one is good. Like Renfro said, you can check your mix wet before you water with it as well. Makes for a very accurate mix and dialing in your crop. We had some reading in the low 5's, some upper 4's. and mixed at 11.5 PH (Sounds crazy I know).. within days, these plants came around like crazy.. You can see them in my grow journal. But I really thought this crop was going to die. We now have a handle on the PH. It does seem to drop off over time, so we have been adjusting (after leveling off) from 7.0 to 7.5 PH to keep it up there by the next day for a reading of 6.5-6.8 (24 hour waiting period before checking results). Bottom line... get one of these tools.... you definitely need it. Hear me now and believe me later.

Thanks for the replies.

I've never had problems in the past so I doubt I'll buy a soil probe. Usually I ph to around 6.5 and rarely have deficiencies.

I know soil/soil less buffers but imo it doesjt do it to the sweet spot. Been growing for decades not that it means much but I definitely notice the difference between phing soiless and not, especially bio bizz which is what I primarily use.but yes the difference is minor and youll do fine without it.imo soil/soiless and run off ph is pretty irrelevant when growing in a medium specifically designed for cannabis, as long as your feed is going in at 6.5 your golden

I ph my water. I'm not very scientific, but I know if I add a little less than 1/4 teaspoon of citric acid every time I water my ph is about right. It works for me. Took this pic last night.
When you pH correct the water do you do it before or after mixing in the nutes? I’m using bio bizz light mix and their starter pack for my first grow. My tap water is 8.2 pH. Should I pH correct my water to 6.2-6.5 then mix my nutes and feed, or should I mix the water, nutes, pH correct and then feed?

So if my water is 8.2 I should pH correct the water to 6.5, mix in the feed, and then water the plant?

I ph before adding nutes. Nutes don't seem to change it much. Not saying I'm right, just how I do it and it works for me.

Thank you. Are you also running bio bizz buffered soil and “organic” bottled nutes? Just curious. It’s so anxiety provoking because bio bizz says not to pH drop the water because the micro herd will level out the pH, but as I said, mine is really alkaline (8.2) so it doesn’t seem wise to not reduce the pH (at least a little bit). I’m thinking by using such alkaline water it will run through any buffering agents in the soil quicker than if I used a closer matched pH.

Thoughts?

I use Nector for the gods #4 soil, and fox farm nutes. I keep things simple. I ph my water to 6.0 to 6.5, add my nutes at 1/2 strength, pretty much follow their schedule, and I always come out with a nice yield. Last grow I lst'd for the first time, and I really liked that, and will continue.

One could use a fish emulsion as a natural pH down for. Alaska Fish 5-1-1 for example. A couple of drops per gallon, can bring alkaline water down substantially.
Really not necessary for natural, organic type mediums, but will also function as a source of microbe, and fungus food.

Thank you, I’m legit starting my first real grow (grew it one time before years ago with a crappy light in a closet), but decided to get back into it seriously.

ive got a bunch of autos, bio bizz light mix, and their liquid feeds, and then was mortified to see my water is 8.2pH.

Thank you for the reply!
Mines near the same 7.8. Robs me ph down if i dont feed with my shit water, like 1.5ml to a gal to get down to 6.0

Your pH goes below 6.0 if you don’t feed with your alkaline water? Interesting, is this because the nutes are so acidic? I ended up finding a purified RO water that sits at 6.5 on the pH meter. For this grow I’m going to roll with that and supplement organic cal mag as needed and go from there. If my pH goes too low I can always supplement with my tap water as necessary... I think...
