My N. sanguinea is doing fabulously but has recently developed a strange problem. The newest pitcher is fully developed, but its lid seems to have stopped before it finished. The lid has seperated from the peristome around about half of the pitcher but is fully fused the rest of the way. I've given it more than several days to see if it would "finish" but it hasn't. The pitcher seems perfectly normal otherwise, is fully colored, etc. Is this just a fluke? I haven't been in the biz long enough to know. Thanks!
