Soil: Looks to be Overwatering. Too much love my friend.
Coco: possible under watering or heat.
But as other said, it’s hard to tell because I don’t really have any information on your grow.
Best of luck on your grow.
Taking a closer look and your light may be too close as you've got a little cupping going on there as well, the top set of leaves are cupping in to protect itself.
could be lght related. Based on what little info is here, only the top leaves are droopy. does this progress downward late in the day? if so, probably the light. Looks fine down below.
