This started as a cutting, and recently I have seen some blackened, dried out sections, especially in the indentations on the stem. I am wondering how I should proceed with this. (I am assuming it is an epiphillum , because it looks like my other ones.) Just FYI, it is in a south window. There are also two epiphyllum oxypetalums in that window, which bloom constantly so I thought this one would be fine there. I only have south light, and I do not have outside access. It is potted in cactus soil with some extra perlite added.
This does appear to be an Epiphyllum, but this will be hard to say for sure. It is either that or one of many closely related species. Differentiation is difficult. Many cannot handle full sun during the peak of the day. This could be a case of sunburn. You can try by letting it get some shade around the middle of the day. If it continues, then you may want to use a fungicide. (I would, just in case, any way)

I think this is an Epiphillum. . The parent plant had a red flower that lasted several days. This is a cutting that is growing energetically, but I am very concerned about the drying out and browning on several areas, especially in the indentations of the main stem, and at the base of some other stems. If this is not normal growth, how should I treat it? Could it be fungal? The plant is growing inside in a south window. I do not have access to an outdoor space nor another window facing another direction. For what it’s worth, I have two oxypetalum in the same window that bloom almost nonstop. I will appreciate any suggestions.
Being an epiphyte, This plant can be sensitive to watering conditions. It can handle drier conditions better than wetter conditions, but appreciates even watering.
make sure that this is in epiphyte soil, amended with some potting soil. This will ensure that it doesn't sit in water, but can still retain moisture.
I don't think that this is a big issue, but if you feel that you want to prevent any disease, then a fungicide treatment wouldn't hurt.

HOWEVER ON THE MAIN SHOOT IT IS STARTING TO HAVE ROOTS COMING FROM THE TOP. SEE PICTURE CAN YOU TELL ME IF THESE ARE ROOTS OR IS IT THE FLOWER STARTING TO BLOOM
There is no photo, so I'm guessing these will be leaf stems. If yours is a starter plant, it may be too young to bloom for a white. These plants put out wavy leaves from the base, then stems with leaves pop out from the base and from other leaves!
