    I think you might have a pest problem. The picture of sibuyanensis looks particularly noteworthy.

    But some of the others don't look like pest issues... It's hard to tell though.

    What kind of water are you watering with? Any strange chemicals or minerals that might have accidentally entered the soil or your water cycle somehow?

    But those black dots on the sibuyanensis look very mite-like. Try scraping them off with a knife.

    I use RO water. I don't think that anything strange is happening with the water. Only some of my plants are doing this anyway, so I don't think it is the water because that is a constant across the board... I'll try scraping the black dots when the lights are back on in the morning and report, though I'm not sure I am seeing what you are seeing. I think the black dots I see are like the little divits that secrete nectar...

    You're right. I did not know that sibuyanensis had the foliar nectar glands, but after reviewing photofinder, I see that they are pretty prominent!

    I still think, though, that some of the white specs on the deadened leaves are sign of a pest of some kind, maybe meal bugs. Also some of the browner fleks around the base of the growth point look suspicious.

    The strange growth of the leaves on the inermis does not resemble any sort of mite problem that I have experienced, and definitely looks like some kind of mineral, or fertilizing issue. Maybe a root problem of some kind. Have these been recently repotted correlating to the disfigurement?

    Also as exo said, if the lighting is too powerful that wont help any either. If your using bulbs that give off hotter reddish light and they are too close, then these growth tips could definitely be having the life cooked out of them.

    Yeah, I don't trust those brown spots on the growth tips. Mites can just suck the life out of your plants like that. I've never used neem oil, but I have used a permethrin-based insecticide to remove mites from my windowsill Nepenthes. It took a few applications, though... and the undersides of the leaves are usually the most susceptible to mites, but they also like the new, soft tissue at the growth points.

    EDIT: Mites would also account for rapid loss of old leaves...
