The symptoms of iron deficiency in cannabis are vague and can often be confused with other nutrient problems. More on this later, but first, let’s look at the common signs of iron deficiency. 1. Early Stage of Iron Deficiency in Cannabis Plants. Iron deficiency is a gradual problem that takes a little time to show itself on the plant.

Crushed eggshells are a great solution too!
