Temperatures Too Cool
As a rule, when plants are exposed to temperatures that are too low, the leaves curl down and around themselves. The most recently formed leaves may become colorless. Because of reduced nutrient availability to the slow-growing root system, the old leaves may turn purple. Raising the temperature, particularly at night, is the only way to correct the problem.
