The leaves on my blueberry plants are turning brown and dying. They start from the tip of the leaf and gradually die back. I've been watering every week sometimes twice a week. They are in containers. I live in north-central Texas and it has been unusually hot here for this time of year, over 100 degrees. I have been using azalea plant food on them about once every two weeks. What am I doing wrong? Any help would be appreciated.

Most likely, it is a watering issue. In heat like that, you will want to water twice a day rather than once or twice weekly, and water the pot for several minutes to make sure it is thoroughly soaked. Plants in containers must be watered daily, even twice a day if temperatures rise above 85 F.
