I have what I think might be some type of fungus (or something else) on some of my Nep leaves.
It ONLY effects the oldest leaves on the plant that have no pitcher anymore. It is also ONLY on a few plants and does not appear to be impacting on new growth.
At first I passed it off as simply the leaves dying but it seems a bit different to when they usually brown off.
Even if it is harmless it is unsightly so any thoughts as to what it might be and if there is anything to combat it?
N. truncata x ventricosa (top and bottom of leaf) - worst effected)
N. (tobaica x ovata) x (bellii x veitchii)
