I've had this tradescantia nanouk for less than two weeks and I'm already getting several browning leaves. From what I've read, it seems this can be either from lack of humidity or too much light, so I'm hoping for advice that's more specific.
The browning is mostly on the edges but it does extend into the leaf on some.
I live in Los Angeles. I took a photo so you can see how close it is to a couple large windows which face south. Though this was taken at night, the plant is in bright light near-on all day.
I watered from above the very first time, before reading that this is not good for the leaves, so I lost many of the leaves at/in soil level. However, I'm generally a bottom water-er anyway so this won't be a problem again. I am unsure of how much water this plant needs - I've read that it should be kept moist but also to let it dry out.
One thing I have read that seems to be consistent is that it likes humidity. I have a humidifier that I run almost every night and if the central air/heat is on, but I'm also thinking of adding a pebble tray.
