Is this a sign of something going wrong? It's happening with a few of the seedlings but not the majority, and it looks like the leaves are always either *entirely* brown or entirely green. (i.e. I'm not seeing any leaves that are like browning on one end but green on the other.)
I'm also seeing this brownness both in more fully developed flytrap leaves as well as in leaves that are just sprouting, as here:
Any idea whether this is an issue, and if so then what the cause of it might be?
Here's some background on what I've been doing care-wise...
Lighting: LED desk lamp, kept on for 12 hours/day
Medium: Mix of long-fiber sphagnum and silica pool sand
Water: Misting with distilled water once a day. Sometimes pouring a bit of water into the tray beneath as well.
Thanks for the help!
