I agree with,last poster,and also soaking in water,like previous poster indicated,that works for me every time.
I remember a week ago i planted in half Gallon growing pots ,young plants that came from a common larger pot,and tho,the perlite potting soil mixture, was wet,I did not soaked the plants in water,because the mosquitoes were eating me alive,and I forgotten,and next day the plants were ,all droopy like that and in much worse shape.
So I took plants in total shade and they recovered,but some leaves just became scorched and died,yet the plants are ok now and growing new leaves.
