I am fairly new here and have mostly just been reading and lurking but I have a few species of Nepenthes currently. I have read what I can find concerning humidity, lighting, soil and watering and beleive I am following those recommendations to the best of my ability. I have noticed in the last few weeks some discoloration and reddening of some leaves of my plants and was curious if this was normal or possibly "sun burn" effects from my lighting. I have included some pics of the plants and one of the currently housing of them...it is an 12x12x18 Exo tank with syran wrap over the screen to keep up the humidity.
The lighting is a T8, 4 bulbs which are the 6500k. It is mounted approx. 12-14" from the plants...I have noticed a fair amount of new growth on most, if not all the plants since the addition of the new lighting setup.
I water (distilled water, no sodium version) with a spray bottle once a day to make sure they are not drying out...could the sprayed water landing on the leaves produce the discoloration?
Thanks for any help or insight.
