Phalaenopsis Orchid Leaves Splitting or Cracked is what this video is about.
The cause of split leaves are a bit of an enigma. I have heard a variety of theories related to low humidity levels, too much water uptake, or a combination like the cuticle layer becoming less flexible due to a combination of low humidity and the drying effect of excessive light levels, while the softer tissues underneath try to grow or swell.
In the environments in which these plant originate, the food supply is very low – some measurements of “throughfall” and “stem flow” from the forest canopy in the tropics has it in the 15-25 ppm total dissolved solids range. Orchids have adapted to having very low concentrations of dissolved solids in their water & nutrient supplies, and accordingly, in their vascular fluids (sap), as well. One plant biologist estimated it to be roughly one-fourth of the concentration of that of terrestrial plants. Now let’s expose them to higher concentrations of minerals in their water supplies, and what happens?
Their coping mechanisms might not be able to control the passive intake, leading to much higher concentrations in their internal fluids, and with the concentration of minerals being higher, the plant will compensate by absorbing a lot more water.  If the rate of absorption of water is such that it outdoes the flexibility of the outer cell layers, then Boom!,  split leaves can occur.
