Peppers require high light levels to maintain structural integrity; lack of photons triggers etiolation, where the plant stretches excessively to find a light source.

Very Common

Temperature Fluctuations

Warm nighttime temperatures can accelerate metabolic rates in Capsicum, causing rapid cell elongation that outpaces the development of lignin in the stems.

Common
