Four pitchers on my ceph have developed yellow/white bleached sections on the lower parts of the central rib.
The ceph in question was recently aquired and was mostly green in colour apart from the peristomes which were red. I've placed it 6 inches under a 24w Cool daylight compact fluorescent lamp and 1 foot away from a north east facing window (I'm located in the southern hemisphere). The pitcher's are turning a red colour but as previously stated the lower parts of the central rib has turned a yellow/white on 4 of the largest pitchers.
Has anyone else experienced this? Could it be signs of the media being a little to dry or a sudden over exposure to light?
