I've germinated several different species of Nepenthes (all lowland) the past few months and most of them seem to be growing pretty well but I've noticed some are turning brown, starting at the tips of the tiny pitchers, and slowly the brown begins to work it's way down the the base of the leaf and then eventually the entire plantlets turn brown and die. Whats odd is that little plantlets seem to be doing fine until the 2nd or 3rd pitcher.
Here's how they are grown:
Lights: About 8" below bright flourescent lights. 6500K 75 CRI 3050 Lumens - 16 hours a day
Temps: Between 80 - 90F all day
Humidity: Around 80%+ The pots they are growing in are inside plastic bags with only a small bit of one end open to keep the humidity below 100% and to keep the temps down.
Night Temps: Around 75F, samehumidity level.
Soil: 100% peat - kept moist but not soggy or water logged.
Ive used no fungicides, pesticides, or fertilizers.
Watering with distilled water
The ones that seem to be having the most trouble are my rafflesiana seedlings but all of the species I am growing seem to be having at least some mortality rate.
What would you suggest I do differently?
