first, here is the patient:
This plant of Nepenthes alata is my very first Nepenthes, that I have for more than 5 years old, and knew, as you can see, more glorious years...
With several moving and disturbing situation here is the result... As you can see at the tiny blue arrow at the upper left, the new leaves are way shorter and curled, slightly 'deformed' (sorry, it can be a wrong word). The second blue arrow (right, at the bottom of the picture) try to show how some leaves are curling up on themselves.
Now, the growing situation: after passing few month in a sunny sunroom, I move here in Rimouski, where it had been placed in a medium lit living room. It was still pitchering, and developing normally but very slowly (non-optimal condition). It began to etiolate, more like a vine growth. Then the growth completly stopped.
When I made my new larger setup in my basement, I place it there. There is a daily humidity which vary from 50% to 75%, 400W HPS, but the plants is not directly under it (but it received a good amount of light anyway). A ultrasonic humidifier is placed right next to my Nepenthes, and they are growing normally if I can say so, even a stunted N. ramispina come back to its growth this week under these condition, but for the N.alata, it is just worst every week.
The new pitchers aborted even before forming, the tip of the leaves are drying. There is some brownish spot under some leaves. The growth never came back. The soil mix is half peat/sand mix, 1/4 perlite, 1/4 vermiculite (if I remember well). No pest is visible.
I now moved it to my windowsill, to have a more constant look over its situation, as shown on the picture.
Any input on what it can be, and how I can set my lovely nep back to growth?
