Hello , I,m your latest newbie to the group
I have a greenhouse full of Epies ! I love them . I just noticed your question jz7297 and I think you simply may have splashed the phylloclades / leaves whilst you were watering it and then the sun has shone through the drops of water and scorched them . The rest of the plant looks o.k. the compost looks quite damp but not too wet . Perhaps it is standing in too sunny a spot ..move into a more shady place . Let it dry out a little before you water it again . Worth saving it , Epiphyllum oxypetalum is a beautiful one !
