Dosing a plant with too much epsom salts will render like conditions.
Anytime you dose the plants with something or change an environmental condition and the plant physically undergoes a change, you have to equate those changes as a result to the physical or environmental change the plant was subjected to. However, I have found some pepper varieties from time to time exhibit leaves like the ones on your plant. I have a couple in my garden that look like yours right now. very little nutrients or fertilizers and no over watering at all. In fact, last night is the first time I have watered them since they went into the ground. It may be that these particular plants require different lighting conditions.
