There are a few possibilities. First, make sure you are watering regularly, but not during the heat of the day. Check whether the soil they are growing in is fertile enough; compost or other fertilizers could help if they haven't been added for a year or two. Also check whether any insects are present on the plants or if visible insect damage exists.
