Why is my plant so tired

At the end of my light cycle my one plant kinda falls over, its totally green but looks unhappy in the last 2 hours of light. It is growing vigorously and the strain is skywalker OG kush , media is verimisoil mixed with perilite, with some hydro corn for drainage at the bottom. It has grown faster than the rest of my plants but looks so fatigued at the end of the day is that bad?

Oh and its on 18/6 light schedule.

Photo from the morning not tired and photo from the end of the day tired would help! I've never had a plant get "tired" during lights on.

Water with some red bull or monster ....

its the strain. a lot of og's do that. perfectly fine. give her 3 weeks. I've never understood why.

boil some chicken broth and feed them

chicken broth chicken broth cha cha cha . every plant will love it, keep away pets they like it too
