My outdoor growing was doing real good until about a week ago. We had started flowering early cause were moving soon and some weeks into it someof the plants started to go limp. The stems and leaves are drooping and some of them are curling up. In the morning they look like they are getting better but by mid day they are drooping again. WE water them and give them nutrients daily because we live in the desert. Could anyone tell us what happened? We even have them covered from the sun by providing some shade. How can we save them. They dont look completely dead, just real tired.
