Answer: Unfortunately, I think your plants are suffering from sun and/or wind burn. It is important to do the hardening off very gradually over about a week, beginning by placing them in a sheltered location out of the wind and in only a little early morning sun. Each day move them to a slightly sunnier location until they are in full sun all morning. At the same time, allow them to dry out (very slightly) before watering deeply in order to wean them from their coddled life indoors. This allows them to become accustomed to the real sun and some wind without shocking them.
