How to detect deficiencies in Cannabis plants

Just like us, cannabis plants require a varied and healthy diet to survive and thrive. They need the right amount of nutrients to fulfil important physiological functions, and if they lack just one piece of the puzzle, growth will slow down and yields may be affected.

Luckily, the cannabis plant does a pretty good job of communicating what it needs. If nutrient deficiency strikes, it often sends out a signal—wilting, discolouration, curled leaves—to inform the cultivator of what it requires.

Before we dive into how to prevent and fix each nutrient deficiency, they are a few important things you should know.
