Hello fellow Nepenthes enthusiasts
I have a slight problem with the above named plant - each new leaf it has produced since acquiring it has resulted somewhat... deformed. The edges are pale and gnarled, almost reminiscent of thrips damage I've witnessed in the past. However, there are no visible pests whatsoever, and the rest of my collection is thriving, except this one - it is excruciatingly slow as well (slower than my villosa, in fact).
I have my plants under 400W of high pressure sodium (new Grolux bulb), at a reasonable distance as to maintain acceptable light intensity (very lush colouration and thick wax cuticle) and temperatures during the day - 70-74F, 75-85% RH.
After dark the temps dip down to 48-54F, at 100% RH, which gives good condensation on the plants.
The problems I have already thought of were the following:
1) The substrate was too tightly packed around the roots of the plants, thus suffocation and stagnation of the root zone due to the lack of air - I have repotted it into fresh, fluffy NZ Sphagnum moss yesterday;
2) Too erratic a photoperiod - I've yet to acquire a good timer for my ballast, and so far it has been turned on and off every day whenever I awaken and likewise when I retire to bed.
I recently sprayed my whole collection with a systemic (Provado, for those familiar with it) just in case it is a pest problem, and so far the product has held up to the positive reputation CP growers in the UK have given it. Whether it will have any significant effect on this plant is a waiting game.
I'm grateful for any suggestions as to what the probable cause is and, if such a thing exists, a remedy.
Thanks all for your time, and good growing!
