Hey all,
as the title says, my Utricularia alpina leaves have been yellowing/browning at tips and I'm not sure why!
Since there isn't that much care information out there it's difficult to tell what I'm doing wrong so any suggestions are MUCH appreciated. :D
It is growing in a terrarium with RH at about +70% and I overhead water it every few days when I see the live sphagnum start to dry out. About a month ago I switched the lighting to a led fixture plus a one bulb t5ho fixture, this may have been when the yellowing first started to appear? I'm kind of suspecting it's sunburn but my U humboltii that's next to it isn't phased in the slightest. Possibly lack of nutrients from not fertilizing enough?
Any tips will help, thanks!

Apparently U. alpina goes through phases of yellowing. If the condition worsens, it is recommended to repot your plant and feed them protozoa organisms.

Thanks for the help @DrNo7 and @carnigrower. I recently got a glass lid for my tank and since then the U. alpina's leaves have gotten more green, though still have a slight yellow tinge at the tips. Not sure if it was the humidity or too much light but it's better now!

I'm glad to hear your alpina is on the mend, mine is well on the way to flowering soon, and so is my jamesoniana, both are on windowsills in my flat.

Kind regards
