I fed my Neps bloodworms on Sept 7th and then again plus a few drops of whole milk on the 19th. Aparently it was too early cos the pitcher fluid is black and the pitchers are starting to fungus on the lids (not all the plants, just the eustachya, fusca and alata). Is there a way to save the pitchers or will I just loose them? How much and how often do you folks feed your plants with apx 3" pitchers? Do you feed all the pitchers or just the newest one?
