In the same way that human beings can be stressed out, it is the same way that cannabis plants can be stressed as well. However, you should not panic, but you should be vigilant in making sure that your cannabis plants get the best care. In the same breath, there are some kinds of stress that are not good for your plants.
Not every kind of stress is bad for your cannabis plants during the growth phase. There are some cannabis growers that purposely stress out their plants for the simply reason of strengthening the plant's resistance, maximizing its yield or accelerating its growth.
There are some types of stress are not good and the plants may not be able to handle the excess stress. Furthermore, this condition will only serve to stunt the growth of the plant or halt it altogether and this will subsequently cause it to die.
Now, let us take at the common causes related to stress on your cannabis plants. The first reason could be that you have not sufficiently watered your plant or you have given it too much water. Either of these is known as ‘water stress.'
No matter which one it is, the leaves will begin to look discolored; soon curling and then wilting. The roots are choked with overwatering and this means that the plant is overwhelmed and this prevents the plant from taking in oxygen and absorbing nutrients.
If you don't give your cannabis plants the amount of nutrients they need, or if you give them too many nutrients, it is cause for stress. Your plants should only get the amount of nutrients it needs and can handle.
The nutrients have to be balanced. If not, the cannabis plants will suffer stress, get discolored and refuse to continue the growth process, after which they could die. In addition, if you give too much nutrients to the plant, bugs and pests will be attracted to it.
The pH Level
Another form of stress that your cannabis plants might go through is the wrong pH level in the soil and nutrient solution. When it is not right, the plant is not able to take in specific nutrients, whether those nutrients are present or not. If the pH level is not right, it can result in major growth issues and deficiencies. The roots could also burn and subsequently result in other issues as well.
Lack of Proper Lighting
Cannabis plants are quite sensitive to light and need certain light cycles to grow. If your cannabis plants do not get sufficient light, their growth potential is minimized. When the light cycle is not sufficient during the flowering phase, then you will have a very bad harvest or yield.
The light cycle has to be consistent. In fact, your cannabis plants should get at least eighteen hours of light while in the vegetative phase and in the flowering phase, they need twelve hours of light and 12 hours of darkness. Stress can even be triggered, if you allow any amount of light to reach the plants during the dark phase. The growth and harvest will be negatively affected.
The roots are very important to the growth of your cannabis plants. It is through the roots that your plants get their oxygen and nutrients for a healthy outcome. When the roots are stressed, it caused damage and also stress to the growth of the plants.
Make sure your root zone does not get too hot or too cold. In addition, be sure that the plants are getting sufficient oxygen at that root zone, which means it also needs proper drainage.
Final Thoughts on Common Causes of Stress on Cannabis Plants
Other causes of stress exist in the environment. Some of these include excess humidity and insufficient air circulation. This could subsequently cause fungus and mold. Try to avoid major stress on your cannabis plants by providing the best care.
