I have 3 phals and all of them have the same problem, as you can see in the attached photos the leaves have some small/big crack on them.
I'm monitoring them to see if they expand.
I'm not sure if it's a disease or something is wrong with watering or medium (sphagnum moss+tree bark)
As you can see one new leaf has these spots too so it's not due to injuries.
Any Ideas?
