I am about 5 weeks into my first grow and am trying to solve an issue with my plants. Overnight many of the leaves began curling up around the edges, forming little canoes. Some of the instances seems quite severe. From what i have been able to gather it could be a mg deficiency, heat stress , or a bad water ph. I moved the 1000 watt HPS that I am using farther away and am hoping that will help. The plants were transplanted into their present home (5 gal buckets) on Sunday and have since been given two waterings and a very light nutrient solution (i used less than 1/3 the recommended dosage) ph'ed at 6.

If it is indeed simply heat stress, should i remove the leaves that have curled in on themselves or will they return to normal? If its not heat , what else could it be? Please help , I am a noob and don't want my babies to croak.

PS, this happened to one degree or another on all my plants , though much more pronounced on the taller ones and on the leaves closest to the top of each plant. The tall ones are Island Sweet Skunk.
