What Is Environmental Stress in Plants

Written by Neal Brown . Updated: February 24, 2021

Environmental Stresses and Their Effects on Cannabis Plants

Though the word has mostly negative connotations, stress isn’t all bad for a cannabis crop. Some pot seed growers intentionally stress their crops to accelerate growth, maximize yield, and strengthen the plants’ resistance to disease. However, some types and levels of stress may have detrimental effects. Here, we’ll look at some of the most common stressors for cannabis plants and some ways to minimize the effects of stress.

Water Stress From Over- Or Underwatering

Experienced marijuana seed cultivators know that watering too much or too often is just as bad as a continual drought. Over or underwatering plants may cause their leaves to become discolored, wilted, and curled. When plants are overwatered, their roots can’t get the oxygen and nutrients they need. Overwatering-related stress is a common cause of growing problems but underwatering is equally concerning, especially in hotter climates like in Arizona or Florida.

Nutrient Stress Related to Over- or Underfeeding

Many cannabis seed growers, especially those doing it for the first time, run into problems caused by over- or underfeeding. Your cannabis plants should not receive any more nutrients than they can handle. Similarly, plants can become stressed when they don’t get enough nourishment or when the balance of nutrients is wrong. Nutrient-related stress brings on various plant problems, from stunted growth to discolored leaves. Overfeeding may also attract bothersome bugs and other intruders.

pH Stress

For optimal growth, cannabis plants need a nutrient solution or soil mixture that’s pH balanced. If the growth medium’s pH level is a bit off, the plants can’t absorb nutrients even if they’re present in the right quantities. Inaccurate soil pH leads to major deficiencies and growth problems, and pH-related stress may cause issues such as root burn.

Light Stress

Marijuana plants are sensitive as far as lighting quality and quantity are concerned. When plants do not get enough light, they simply cannot reach their full growth potential. Low light during the flowering stage is sure to lead to a substandard harvest.

When cultivating cannabis, in Missouri or Utah, it’s crucial to put the plants on a consistent light cycle. Plants should get 18 hours of steady light during the vegetative stage, and during flowering, they should be on a 12/12 light/dark cycle. When light cycles are inconsistent, the plants become confused.

It’s important not to interrupt the dark portion of the light cycle, as plants are easily stressed during the flowering stage. When the lights-off period is broken, the plants will regress from the flowering phase into the vegetative stage. This adversely affects the plants’ health, growth, and yield.
