Hot soil refers to soil that has been excessively fertilized which can lead to various issues in your garden. Novice cultivators often encounter this problem due to their enthusiasm and inadvertently providing plants with more fertilizer than they can effectively metabolize. This creates a condition called nutrient burn, or nutrient lockout, or too much of one nutrient blocks of plant being able to uptake other essential nutrients.
These excessive nutrients are retained in the soil and creates a potentially toxic environment which is referred to as “hot soil”. This does not describe the actual temperature of the soil but rather a toxic environment.
Cannabis plants will begin to exhibit symptoms from hot soil rather quickly. Learn more about what hot soil is, how to recognize it, and how to fix it.
