Make sure the pot isnt to hot. If it is try to cool it down. move The plants to the shade. Water before sunset or early in the am so the plants are moist for the day.
It can overwatering, stop watering the plant until your growing container is light and growing medium looks dry on the top.
Sometimes is better not too water so much.In That way, you can control the water intake.
