What is the most accurate and easiest way to check nute water. I have like ph meters but still get yellow tips on some leaves. I also noticed they aren’t very consistent as advertised. Any help is appreciated
I use a 20$ ph meter and calibrate ones and everything is fine for me!
Maybe you need to calibrate again!
The yellow tips can be a start of a nutrient burn or a salt build up! Check the ppm of the feed and the ppm of the runoff!
