Monstera deliciosa just got checked.
The plant appears vigorous with good color and active new growth. The leaf you pointed out is leaning downward in a way that commonly happens on Monstera leaves as they mature and get heavier, especially outdoors in bright indirect light. I do not see clear signs of rot, burn, major nutrient issue, or pest damage in the photo.
What to do today
No urgent treatment is needed. Just keep it on a steady watering routine and rotate the pot occasionally so growth stays balanced.
Also possible, but less likely
What would prove it
Watch the leaf posture
If the leaf stays firm, it is normal. If it starts to sag, soften, yellow, or feel floppy, then inconsistent moisture or root stress becomes more likely.
