you can also cut of a few branches, and clone them, so instead of 1 fire lady you have 3 or 4 or more fire ladys =)

ok do what llamaman says you dont have to kill her just cut the buds out, and put it in a 24/0 for a few days then 18/6, and she'll get better, try to leave a few leafs, so it will still make photosyntesis

and next time dont plant only 1, (i get too emotional if i only planted 1) then i plant a few so i dont get sad...
