Drying Kalanchoe leaves

Hello,
I am new to keeping plants. I have a problem with my Kalanchoe blossefeldiana plant. I have it since spring and it finished blooming a couple months ago, it let go all of the original leaves, and now it has a bunch of new stems with new leaves. But many of the leaves have these scrape-like spots on the back side that look more like a physical damage rather then a pest. Smaller inner and lower leaves quickly get dry and yellow and fall off, but many big leaves have the spots, even if they look healthy on top. I can't find anything similar anywhere online to determine what is causing it. 
I keep it on a desk next to a window, so it gets a lot of daylight but not direct sunlight, but it still grows quite tall. Watering after the soil dries out. Didn't fertilize. I am not sure what the soil is, as I got it as a present.
I have two small cuttings with the same issue.
If anyone can help with determining the cause, I would appreciate it a lot. Adding some photos as well.

    Think they’re definitely in need of more daylight. I wouldn’t be too worried about the marks. Few plants have perfect leaves.

    Thanks for the reply. I was worried about the amount of daylight they are getting, but I live in a small apartment that only has east facing windows, so I don't have too many choices. And, since the days are becoming shorter, I am worried that they might not do well during winter. 
    I also have some small cacti and a couple of orchids, that sit in the same area, but they all seem to be quite well.

    The leaf that's detached from the plant looks like it has had some physical damage (perhaps it was knocked or pushed against a wall or window).  Other than that, they look fine to me!  Loss of some lower leaves is normal for most plants.  Give them as much light as possible over the winter, and not too much water.  In spring I think I would give the mother plant a bigger pot and some fresh compost, and pinch out the tips of the cuttings to encourage them to branch out from lower down (they should put out new stems from where the leaves join the stem).
