Leaves around buds curling but not dry

[HMCSBudba]

I have an unknown strain from seed germination in early February put in ground first week of May. Fox farm feeding schedule followed for grow big and big bloom. Over 6" of rain in the last week. This sativa started budding within a week of being placed in the ground. I am in the SE US. Temps have been 80-90 F with direct sun to 60 at night with mild days below 80 this week. I have had a couple of successful grows without additional nutes but small yields. Buds on the neighbor plant are perfect and beautiful but I know it's very early for budding. My question couldn't be found on the forums so I wonder if the curling is from heat stress. I imagine the sativas will reveg based on threads I have read. Will the buds be ok upon reveg on the curled leaf plant? Any advice would be greatly appreciated. Last couple are 2 indicas neigbors who want to start budding. Thank you very much!
