Leaves on a healthy indica often droop in the last hour before lights out and briefly after lights on, which alarms new growers into watering or feeding something that is fine. The plant is relaxing for its dark period, and the leaves lift again within an hour of the lamp returning. Photos comparing this normal evening droop with real overwatering and underwatering on indica seedlings are set out on https://kushindicaseeds.com so the three are easy to tell apart. Checking the plant mid day gives a more reliable picture.
