I have not yet upgraded my ph meter to an apera ph60 (or equivalent) as suggested by Bluey and Rwise et al, so I’m stuck with my old meter. Nevertheless, The ph reading for this plant and with this meter is 7.0.
I measured my other plants for comparison. Out of 9 plants, 7 had a ph of 7.0, one was 6.7, the other 6.8. (The 6.7 is one that is in flowering phase.)
So, the meter does seem to be repeatable. As far as accuracy I can’t say. ( I do plan to replace it with a better one. I just haven’t done it yet. Your advice didn’t fall on deaf ears.)

You measure the pH inputs. Easy as. Don't bother with measuring runoff pH.
Don't ask me how to use a pH meter that is +/- 0.25. I'd bin it.
Apera have an Amazon store. Get storage fluid and calibration fluid in the same order.
If you are giving nutes also consider the PC60 instead of the PH60.
Don't bother with the Bluetooth model.

ps. I ran 6 liters of water through this one which is 20-100% more past the “pouring out†point, depending on where that is, 3 or 5 liters.
My hope is that I didn’t overwater it too bad. The leaves are curled up like a claw now. It’s a mystery to me as to how the soil knows when to let the water flush the soil and when to hold the water and cause problems.
Thoughts?

Huh? I see a healthy looking plant. Looks better than mine! Seriously! I have pH tips. Where is your clawing? If those leaves mean you have Ntox, I have Ntox and have had Ntox in pretty much every plant I have grown since getting my groove together.
Are you giving more than recommended nutrients? Are you giving veg nutrients to still-hot soil?
Plants move and do things when they grow. I mentioned a time-lapse making a plant look like it was waving like a bird. That is not a joke. When you see plants turning colors other than green and taking other than fan leaf shapes, worry.
Now, check manufacturers recommendations. I know you're working with equipment issues. When it comes to flushing, that might not be the best toilet.

No I’m not using nutrients (other than what is in the soil already).
I just watered it (a lot, trying to flush out N as I explained), and the plant has just entered flowering stage. Do you recommend dropping the ph to 6.3 now? What are the benefits to dropping the ph now verses just letting the plant flower and finish its life with a ph of 7.0?

Ok. Once it starts to flower (you see flowers) raise your pH slowly from what it should be in veg 6.2 to 6.5 to flower pH of 6.5 to 6.8.
Give it another flush. You want very little N in that soil heading into flower. You may need to suppliment some PK at ¼ to ½ strength at about 3 to 4 weeks into flower and keep that up for a bit.

You can't remove an excess of nitrogen from a plant by flushing the soil.
Your flushing the soil to remove the excess N from the soil as you don't want that going into flower.
Your plant is packed with N and if it needs some it can't get from the soil it will scavenge it from the lower leaves.
Edut. Yes flushing the soil will stress the plant. You do it once properly, not 6 times half hearted. It will recover quickly.

Bluey thanks for the guidance. I wasn’t planning to add nutrients, but after learning more about it, I think I will. And adjusting the ph is needed. And I definitely need a meter.
I feel certain that a lot of nutrients have been used up in the plants (which are) blooming, plus I was planning to keep some other plants in the vegetative state for longer than normal. These will definitely need help. Thanks

I reconsidered and am going to use nutrients. You suggested the PC60 vs PH60 if using nutrients. Does the PC60 measure NPK as well as ph? (The apera website doesn’t say specifically.)
edit: the apera website does provide an email address and I sent the question to them. The PC60 measures TDS but the website doesn’t specify what the total dissolved solids are. [i’m looking for an instrument that measures nitrogen, potassium, and phosphorus in the soil.]
