I just bought this massive plant Epiphyllum oxypetalum from a nursery a few towns away from me. I am reading and watching everything I can to grow her. I did repot her but only in a pot slightly larger then the hanging one she came in. I have no idea when she was watered last and how much to give her ( but believe it should be every two weeks) I pinned her up a bit since she’s a climber outdoors. I don’t have her by any doors or vents. I will show her light source. But I do not have a good south facing one. Less then a week ago I brought her home and cleaned her with water and need oil due to some black spots. Today I woke up and see some of her tips are discoloring 😫 please tell me she just needs water. An app is saying root issues. I gave her maybe less then a cup two days ago with some fertilizer liquid. Any feedback or suggestions would be amazing. I love and adore her and want to do my best.
Thanks
