Why do leaves turn yellow...???

• It is very common for leaves of plants to turn yellow. It happens due to many reasons. The most common is the moisture stress, which can be from either over watering or under watering.

• Another reason is not getting enough light. This is because the rate of photosynthesis is limited in low light, but as the light increases, photosynthesis increases as well.
