My plants have had a slight droop both from over watering and Underwatering. When they were under watered they typically perked up fairly quickly after a good soak, also my leaves would feel a bit dry too. Where as when over, they felt full and heavy. You mentioned trimming lower area to boost the light penetration, I think many people would also recommend trimming just a few upper fan leaves if they were blocking your bud sites.
They do look a little droopy and tired, I see you're at 24 hrs light, perhaps giving them a 4 hour dark period would give them a bit of rest and relaxation to recooperate. Also you're only 5 weeks in so there's much time left for them to really bulk up and fill in.
I really hope they turn out well for you. Happy growing.
