Ok i'm hoping some of you Nepenthes guru's can help me out here. I've got a Nepenthes that I bought at my local nursury(so its probably not some rare ultra low/highland variety), it almost looks like some hybrid ventricosa.
As of now I grow it in a 30 gal tank, it gets some natural sunlight, and is lighted by a grow-lux and 2 cool white bulbs. Temperature is probably like 75-80ish. Not too much of a temp change. Humidity is always like 75% or above.
Anyhow, my Nepenthes seems to be doing pretty good about making new leaves, since it has grown 3 new leaves since I bought it. Their all a nice dark green color. The problem is at the end of the leaf where the tendril for the pitcher forms. On all 3 leaves the tendril part is about an inch long, and at the end of the tendril it is kind of a silky brown. Now the first leaf that grew has had the tendril with the silky brown end for about 2-2 1/2 weeks now or so, and no sign of a pitcher forming yet. Anyone else have had this happen before? I'm kind of thinking it maybe needs a lower temp drop, but would love to hear any ideas from you all on why its doing this..thanks.
