Bent/broken leaves near base

[SouthPark]

Most welcome Jak. The only thing(s) I can think of for the moment are ----- variation in conditions around the plant.

If it is an indoor environment, then could consider if the plant experiences any significant changes in conditions - such as if heating system of the house or something turns on and off (temperature/humidity changes). That is - around the times of the growth of that particular leaf.

Also, whether the orchid's position changes whenever watering is done. Is the orchid's position (leaves etc) placed back in roughly the same spot as it was before - thinking about variations in lighting.

Maybe that won't have any affect, but could just consider that too. Also, temperature of water used during watering - such as - is it around the same temperature of the plant.
