Hi All,
I had this happen to me a couple of times. A healthy plant would
just up and die, starting by looking rather weak and then blackening.
I think it has to do with the light a given plant is receiving.
After I boosted the light levels, either by putting the plants out
into the sun or by moving them closer to the light, the sickly plants
that hadn't died yet came back and grew much faster.
I do beleive I've never seen a Ceph stretching for light so don't look
for this as a sign it is not getting enough light. The pitchers will
get a nice red outline on them if the plant is getting adequate light.
