I will note that!If you get a digital, DO NOT get a cheap Amazon one, I only trust Blue Lab, just calibrate and your golden
Also if your new to hydroponics and ph testing, I highly recommend always premix your solutions a day ahead of time and recheck ph, as SOME nutrient lines will "bounce" or change ph after being mixed a while, as a rookie long time ago took me forever to figure that out. No one told me.
I personally prefer the general hydroponics kit, but digital blue lab for shore!
Let them (plants) tell you, you'll see dude, awesome stuff
EDIT: OR APOGEE , they are reliable as well if blue lab not available over there, I take it your in UK?
Edit: another tip, if use litmus, NEver dip drop onto paper, and only after solution is really well mixed and sat for while. Dipping litmus in recently mixed solution will not be accurate, trust me
I was told that with mineral ferts you should premix, but with organic ferts I was told is not ideal because they deteriorate or something??
Another question, if I use organic ferts, and the watering solution is brown, assuming a pH of 6, the liquid will turn Yellow clearly? Maybe overthinking this because of the solution color, any tutorial I find is people testing the drops in plain water
Edit: I'm from Spain, blue lab should be available
