Im having a huge problem with my neps right now. They seemed to be growing OK for the first half of the year and now they look very very bad. I've already lost N. sanguinea and fusca (baby) to the same symptoms.
I live in Singapore, which should be OK for neps, however, today i got a hygrometer and things didn;t look good.
Temperature: 30 degrees celcuis +- day and night
relative humidity: 55% !!! This is unexpected, could this be the problem?
Light: artificial fluorescent lights, 4 tubes
soil mix: 1:1:1 peat, perlite, hydroton (1cm balls)
water: plants kept moist. When i put my finger in, the peat sticks to it. Some plants are kept in a tray of water.
Circulation: live in apartment, windows open, should be ok
clip x eymae
bical, was growing and pitchering and increasing in size until now
sibuyanensis, produced 2-3 ok leaves, 1 had forming pitcher until now.
produced a 3 inch pitcher, that continued like that.
The problem: A reduction in leaf size or blackeing of leaves from the bottom (oldest leaf) up, until the last, growing tip.
The 'easier' plants like hookeriania, rafflesiana, max x vent are fine.
please give me your thoughts/experiences!?
