Everyone else is doing reasonably well, but these guys just seem perpetually angsty (I have two and they look pretty much the same):
From this chart, posted by The_NorthEast_ChileMan here...
...it seems like the discoloration could be molybdenum deficiency? Maybe? Some of the other plants have similar discoloration, but not as pronounced.
And could excessive humidity be responsible for the curling? I don't think it's over- or under-watering, because it does this whether it's dry or wet, and it's looked like this pretty consistently regardless of how or whether it's been fertilized.
Any other ideas would be more than welcome.
