I have clump of drosera (needs identifying) potted in 100% peat moss. The problem I'm having involves some leaves turning a red-redish brown coloration which lack the dew that characterizes sundews. I have the plant in a terrarium that gets upwards of 18k lumens of light. I guess I just need to know how fix the miscoloring and the lack of dew. I also heard of how some drosera get a black center, which is supposedly the build up of some acidic elements any tips? Some of the plants flowered but the flowers, to my knwledge, never opened.
