Stress in marijuana plantsis caused by imbalances of the plant chemistry. Generally plant stress disrupts the normal chemical reactions happening within the plant and causes ethylene ( the aging hormone) to start developing in the cells.
A plant likes to have an average day with no surprises on any day of its life. Any unusual event in the marijuana plantslife will change its internal chemistry and result to slow growth. Some of the stress causes are
1) WATER STRESS: There is a lack of water or too much water for the plant to absorb. Water stress in marijuana plantscauses abscisic acid to build up and closes down the stomata.
2) NUTRIENT STRESS: Usually cased by too much, not enough, or an imbalance of the nutrients. This can attract diseases or nematodes (type of worm) and disrupt root function.
3) Mineral Stress: It is caused by mineral imbalance in plant tissues, usually due to nutrient problems or by adding to re-circulating mixes. This causes plant growth to slow. By the time the results are visible, the problem is already very advanced. It usually takes a week or so to recover from mineral stress.
4) PH STRESS: The PH of the nutrient solution is changing all the time as the plant uses the minerals in the surrounding nutrients and as the water is transpired by the leaves and evaporates from the nutrient solution. Wildly fluctuating PH will reduce the marijuana plantsnutrient uptake and cause deficiencies
5) AGE STRESS: AS a plant gets older, its nutrients need to change. A tissue analysis will show the plant using totally different quantities of each nutrient as it ages. In highly supercharged garden systems, the nutrient fed to marijuana plantsis different for each week of growth. Mature or ageing marijuana plantsneed far less nutrients.
6) IRREGULAR LIGHT CYCLES: These will change the hormonal balance in marijuana plantsthat use the length of light and dark to tell when to flower.
7) PLANT DAMAGE: Any damage causes the plant to change its chemistry to repair the damaged are of the plant
ROOT DAMAGE: Either physical or chemical causes the plant to divert its chemistry to keep the roots advancing and creating new root hairs to absorb food. Roots cant actually rebuild themselves when damaged; they just seal off the damaged section and move around it.
9) Environmental extremes / Diseases: The can cause a plant to age and flow prematurely, a female plant to produce viable seeds without being fertilized, or just cause poor growth.
