I took it to a friend that owns a plant store here in SF, who also has a nice Nep collection. He does not think its sunburn, due to the fact that it has been in this spot thru the summer months when it was much hotter and the sum much more intense than now. He thinks its some type of chemichal issue. We think we narrowed it down as I talked with him more. Its not the mazsea, the solution is very very diluted and all my other 30+ plants (including another Rajah x Mira) get the same quick spays once and a while, also I've been doing this to this plant for over a year and a half.... so it must be something more recent, as you can see most of the lower leaves are not effected or very much compared to the more recent ones. We think its the Osmocote pellets that I've experimented with. After reading a blog by Peter D'Amato at California Carnivoures, I thought I'd give it a try. I put a pellet in the pitcher when it had one as well as my others. I haven't seen any difference in any of the plants so far, but I think this plant might have been effected negatively. It's really the only thing that has changed in the last few months. Perhaps this Nep is more sensitive than others
I have repotted the plant, sprayed it with a systemic pest killer spray, moved it to slightly less sunny spot, and raised the humidity. I think I covered all the bases there. There is a new leaf forming, and fingers crossed that it is healthy. Also interestingly enough when I was repotting, it appears there is a basil starting to grow just beneath the surface of the soil.
I will keep you posted as to its health the next little while
