OK. So i'm growing in the desert. I have had my fair share of heat stress problems because the weather where i live is... chaotic. One day it was 90 degrees Fahrenheit...it had been that way for about three weeks. And the next day the wind blows in a cold front and it's 40 and raining. The next few days it hasn't broken 80 and my plants are somewhat droopy. Could this be stress form the cold?
