Nitrogen burn cannabis
Nutrient burn can be caused by:
Nutrient burn can affect cannabis during any stage of growth. Prevention, identification, and remediation are all essential pieces of knowledge in the cannabis grower’s arsenal.
When measuring nutrients, use a measuring device that has a set capacity. If the mix is 10ml per litre, use a 10ml kitchen-type measuring spoon, for example. Take the human error out of the equation as much as possible. It is very easy to overdose if you misread a measuring line on a jug or cup. Looking down on a measuring line will always be too much. Make sure you always measure at eye level.
Early indications of nutrient build-up prior to burning can be:

  • Mixing nutrients stronger than recommended during any phase of growth
  • Overwatering; plants need a dry period to function properly and access oxygen
  • Using bloom boosters too often or in too high a concentration
  • Using growth stimulants too regularly, causing dwarfism and burning due to excessive nutrient uptake

Nutrient burn in cannabis could be called the “novices lament” or “over-enthusiasm backlash.” Nutrient burn is a type of stress caused by overfeeding your plants or mixing nutrients too strongly. Novice growers are often under the misconception that more is better. This is very untrue. Often, burning can be caused by simple human error. Luckily, the condition can be fixed before it demolishes your crop. That said, it can damage a crop at any stage of its development.
Buds can be affected by nutrient burn as well. During the flowering phase, cannabis changes the way it uses nutrients. The need for nitrogen drops almost to zero while the demand for other compounds like calcium and magnesium increases. An overdose of any kind of additive will cause the same type of burning features.
One of the numerous benefits of growing in organic soil is that it provides a buffer zone of organisms around the root system. Soil grown plants are more resilient to overfeeding and other stressors. A well-prepared organic soil really needs no nutrients for the entire grow cycle, removing the danger of burning altogether.
Prior to returning to a regular feeding schedule, use a specialised plant tonic to nurse the plant back to health. The root biosphere will have been affected, as well as the green parts of the plant. Tonics with silver nitrate, humic and fulvic acids, vitamins and minerals are ideal to restore plants to health.
Over-enthusiasm with nutrients can burn marijuana plants. Knowledge is power when it comes to big buds. So, how to prevent and treat nutrient burn?
