I need some help with my Utricularia. They grow and produce leaves, but they grow very slow. I have a 3 inch pot of U.livida and it has taken over 1 month just to get about half of the pot filled. The same thing has happend with my U.livida. The leaves are not a lush green, but rather a more sickly green. I have tried 50:50 peaterlite, 50:50 silica sandeat, and pure peat moss as my growing media, and none seem to help. They always have a plentiful supply of water, and have a temp. around 78-82F with humidity of 35-45%. Here are some pics of what they look like.
