Hi,
I'll jump in with my two cents' worth, and suggest that maybe the air is
too humid (although I realize that inside in the winter, that seems
unlikely). It the plant isn't transpiring, it isn't able to bring
nutrients up from its roots and will die of malnutrition. Maybe next
time you can start them when the season warms and grow them in a
sheltered spot outside?
