Kohlrabi leaves turning brown?

Kohlrabi    Calgary, Alberta

Would high temperatures be causing leaves to turn brown? I can see no sign of spotting or bugs on the plants.

Are the plants getting enough water?

Hi Cher,

This kind of looks like a nutrient deficiency in the plants. In my research I grow other brassicaceae plants in pots, and if I let them go too long in the pots they use up the nutrients in the soil and the lower leaves begin to turn a pale color like in your photo. So perhaps you need to supply more nutrients to your plants (Nitrogen, phosphorus, potassium, and trace micronutrients).
