Recently my Cephalotus 'Hummer's Giant' hasn't been looking so good. A lot of the pitchers are turning yellow. I'm hoping it's not Pythium and is instead just the result of not enough water. The weather in San Francisco has been getting warmer lately and this plant is starting to receive some later afternoon sun (in addition to the T5 bulb it grows under all day). It is growing in an open top growing chamber in front of a large window that is cracked most of the time. So there is always some airflow happening. It's companions in the grow chamber are Nepenthes and Helis. Everyone else seems happy. My Ceph seemed to be doing GREAT until about a week ago. I should also mention that the Ceph is growing in the Charles Brewer mix. Here are two photos I took before I trimmed off a lot of the yellowing pitchers.
