Similar to asking why an athlete has a bead of sweat on his forehead, she looks very healthy, rigid turgor, tells me she is going hard, not too stressful, just right, its a thing of balance to maintain, between cooling over the long 18+ hour days, anytime a tip slightly curls up is a cooling thing, 10% of water used during daytime is for cooling, just cool her off a degree or two, or raise the light in 6" increments honestly she looks good. Nicely grown.

My guess would be that it’s getting too much light or the light may be too close to the plant. The plant is trying to protect itself by curling the leaves. Temps and RH look like they’re on point. I would try raising the light or backing off the intensity. A plant this age only needs 250 to 300 PAR/PPFD at 18 hours per day. Hope that helps. Good luck with your grow.
