I add fertilizer directly into the pitchers of my Nepenthes, but on N. fusca I've got free floating algae. Of course this is competition for the nutrients, but when the nutrients are used up won't it just die and release anything it's accumulated? Or is this bad? Would an algae coating on the pitcher walls have negative effects on the glandular system or something?
And why only on one pitcher, which isn't even in high light compared to my other pitchers?
