It looks like cold burn or maybe transplant shock. Your best bet in saving it is raise the temps and humidity, but it looks like it may be to late.  Good luck. Mitchell |

Thank you for answer.
This can not be from cold. Temperatures are: 27-32*C at day and 18-25*C at night. Humidity is never lower that 65%.
Now I discovered that it may be soil. My bicalcaratas in sphagnum moss are growing quite good but the ones in mix (peat, bark, coco chips) are all dying. But rafflesiana and ampullarias grow very well in this mix.
Today I have repoted sick bicals to fresh sphagnum + perlite.
Anyone have any ideas?

It does look like the roots are sick, drying the plant out. I don't know why that soil isn't good for them, but that does seem to be the case.
BTW, 20 C sounds a bit chilly for N. b..

Dave - thank you for answer.
Yes I think that is the case. Besides I think Bicalcaratas was weak when I received them.
I have potted them few days ago to sphagnum with perlite. Maybe they will recover but now they look very "tired".
I wonder what was wrong with my mix? Rafflesianas and Ampullarias grow very well in the same mix. But I see that something was not alright because there was small flies when I put plants in this mix to higher humidity...
Dave You say that bicalcarata doesn't like temps under 20*C?
Thanks for help!

I notice you have coco husk chips in that media. There are varying qualities of husk available and I myself found it out the hard way. I would say that is the problem. See if you can replace the media with a sphagnum moss/perlite/fir bark mix. If you don't have easy access to sphagnum, see if you can get peat moss and appropriately mix it with increasing amount of bark and perlite to keep it relatively open.

Sorry to write so late. Just wanted to tell that these bicalcaratas have recovered. Thanks everyone for help! I have repotted them to my standard mix (NZ Sphagnum + pelite) and they like it very much. Only one have died - it was very sick before repotting. Few pics as reward:) This was the most sick plant (sorry for quality):  Small pitchers on other plants:  Bigger ones:  And the biggest one - turning almost red:  |
