These 3 pepper plants have been growing since late may when i transplanted them from a six pack. They have produced about 15 lbs so far and are still setting peppers. The leaves have started yellowing and falling off, the tips of the leaves are also getting black/brown. The is happening on all 3 plants. The plants were fertilized in mid June with bone meal and epsom salts. They are in containers. I've been watering every two to three days. What is this?
