I am not one to suggest or support any such tools. I feel that ph meters do MUCH more harm than good.
Getting an accurate reading is the first part of "not likely". Making the proper fixes even if you do get the right reading is probably VERY unlikely.
Companies want to sell you gear, I have shelves of meters and gauges and papers and fixes and all.....collecting dust.
The best thing to do is get a simple water filter, (I use an RO filter) and never adjust my ph.
I don't even waste my time trying to read it because then what?
One THINKS they can fix it but they never do, they always just make it worse. really it's true.
It is much better to mix your nutes in your 5 gallon, 10 gallon or 50 gallon container and water. No adjustments.
Different nutrients uptake at different ph and if one keeps in the recommended window of 5.6 for hydro or 6.3 for soil, there will be prime and trace elements outside of that window that can not uptake and you will be required to make a mid course correction.
You should never have to fix things, if you do them right in the first place, you never will need to fix them.
So proper nutrient levels, proper aerated water (Fill up reservoir day before and run a fish pump through it to oxygenate it and burn off the chlorine that comes out of the tap)
Add your nutrients, ( a little lighter is always better than a little heavier) more is NOT better, more is worse. Then water and leave it alone.
Like I said, great job for the first run, next time you will do half as much work and worrying and have twice as good a flower.
