Looks like 100% Potassium deficiency to me. Usually caused by over-watering or heat, or both and may clear up on its own after the period of stress is over. If you only see one or two affected leaves near the bottom of the plant, and the problem isn't spreading, I wouldn't worry too much about it! I would however give the plant a good flushing with PH'd water.
