|Browning leaves can indicate heat stress or a fungal disease. Even though your plant is getting adequate water, summer heat can turn the leaves a brownish color and they can droop and feel soft to the touch. Crispy brown leaves can indicate sunburn, wind burn or a root problem. I'd cut or pull off the affected leaves to see if the plant doesn't produce new healthy leaves if their places. If not, overly wet roots might be the cause of the problem. Adjust your watering schedule to allow the top of the soil to dry out between waterings. Hope this helps!
