To properly diagnose a cannabis or weed plants issues, we must first narrow down the possible causes through a process of elimination. The first thing you should do if you cannot identify the type of deficiency based on physical signs is to measure and test the runoff water. Some physical signs can be narrowed down in our yellow leaves tutorial:

Runoff is water that is drained through your soil and it gives you an idea of what the levels of ph and nutrient concentration the plant is actually consuming. When this is out of a proper range, this cause nutrient lockout which will result in ugly dying plants. Another issue is excess concentrations of nutrients and this is measured using a TDS (total dissolved solvents) meter which measures ppm (parts per million). When too many nutrients or salts are in your soil, this can also create problems such
