Abiotic stress include:
- the light (excesss or not enough light)
- the air or soil humidity
- the temperature (too high or too low)
cause nutrient deficiency on plant ?
that is a question with a very wide answer. most of abiotic stress affects plant water balance (the net of water absorption and transpiration) climate factors such as air temperature and humidity as well as solar radiation affect plant water loss through transpiration. the net energy intercepted by the plant affect the amount of water loss. moreover, the main stream of water uptake is driven by transpiration rate and this determine where some nutrients are accumulated in the most transpiring organ of the plant (the leaves) compared to the other organs and this also results in some local nutrient deficiencies such as Ca in the fruits which appear in the form of Blossom End Rot (BER) in tomato and paprika for example. . on the other hand, abiotic stresses like salinity or drought in the root zone can affect the absorption of nutrients resulting in nutrient deficiencies even if the nutrients exist in the root zone. Temperature of the root zone plays also an important factor in the rate of absorption of both water and nutrient and may cause some nutrient deficiencies in the plant. please read the following for the explanation of some factors on the incidence of BER in relation to different environmental factors.

The natural environment for plants is composed of a complex set of abiotic stresses and biotic stresses. Plant responses to these stresses are equally complex. Infact , both of them compliment each other by moderating the impact of abiotic stress on susboptimum nutrition and likewise suboptimum nutrition will accentuate the magnitude of abiotic stress ..

Every plant require a special kind of climate so it affected by abiotic stresses like heat stress, cold stress
high temperatures can increase the rate of reproductive development, which shortens the time for photosynthesis to contribute to fruit or seed production. I also will consider this as a heat-stress effect even though it may not cause permanent (irreversible) damage to development because the acceleration does substantially reduce total fruit or grain yield.
Cold stress affect the leaves badly, photosynthesis will b reduce, decreasing carbohydrate than hence nutrients
During antibiotic stresses the stomata may remain close which affects water transport. As nutrients come into contact with roots in a dissolved form in water so whenever rate of water uptake changes nutrient uptake also changes. This is also linked with photosynthesis in the same way.
Environmental factors cause nutrient deficiencies, even in fertilized fields, as the physiochemical
properties of the soil can lead to a reduced mobility and absorbance of individual nutrients.

Abiotic stress such as salinity make some nutrients immobile and the plants can not absorb it. also drought or water logging reduce the ability of the roots to absorb water and nutrients resulting in nutrient deficiency. chilling stress reduce the viscosity of the water and the metabolic rate within the plant and lead to the same deficiencies.
Abiotic stress acts as predisposing factor to development of nutrient deficiency. This is the very reason , some times, it is very difficult to distinguish between the two factors, because of overlapping symptoms ..
