I saw today that my Darlingtonia pitchers were slanted sideways and on further inspection found that they have gone flacid (for lack of a better word) and are sligthly browning. This has happened to both new pitchers that have developed since it woke up from dormancy and the one developing at the moment, however the older pitchers from last year are the same as they were.
It's been growing in 1/1 peat/perlite and I recently repotted it into a larger terracotta pot. I read today that terracotta can absorb minerals and nutrients from previous soils in it so could this explain it? I repotted it today into a plastic pot with a higher amount of perlite in the mix and saw that the roots seem to be completely fine.
I water it, along with all my plants, with rainwater and it sits in about two inches of water and gets watered from above on hot days or when the waterline drops.
Recently the weather has been very hot however no more so than last year and I took the same precautions to keep the roots cool.
Thats as much relevant information as I can think of, if pictures are needed then I can provide them although they won't show anything that I haven't attempted to explain.
Does anyone have any ideas what is happening/if it is bad for my plant's health/how to prevent it?
As always, thanks for any advice!
