When Less Is More: The Harms of Overfertilizing Your Cannabis Plants

Research shows that plants absorb excess nutrients even when they're not needed (called ‘luxury consumption’), which can even inhibit uptake of other nutrients. Learn how to meet plants’ needs while avoiding problems and saving money in the process.

Luxury uptake can result in nutrient antagonism. For example, high phosphorus can result in iron deficiency (A), and high calcium can result in magnesium deficiency (B) even when adequate fertility is available.
