Safe to say I'm Hella confused when it comes to this part of growing.

I will have a blue lab truncheon and I've seen people say it's country dependent on converting your ec reading to ppm.

Also when testing ppm obviously you measure your water then add the nutrients needed to get to desired ppm for each stage of growth but do people measure run off Also or is that not important.

Find it's conversion 0.5 0.64 or 0.7 to convert between EC and ppm.

Never read runoff it won't work that way just give what is needed.

EC is a universal measurement, which is why I prefer to use it. All ppm measurements are converted from EC based on the ppm scale you want to express the reading in.

Measuring runoff in soil is pointless, focus on what you put in for feed not what comes out. GL
