Signs of light stress in plants can manifest in several ways, affecting their overall health and growth. One of the most common indicators is leaf discoloration, where leaves may turn yellow, indicating chlorosis due to insufficient light or nutrient deficiencies.
Stretching or elongation, known as etiolation, occurs when plants grow tall and spindly as they reach for light, often resulting in weak stems and a sparse canopy. Reduced growth rates and poor flowering or fruiting can also signify light stress, as plants struggle to perform essential metabolic functions.
