I want to say too much light, but I could be wrong.

Slow board, ain't it?

That was my thought too, so I moved the plant to the edges of my light table. On furthur reflection, I'm not sure if excess light is the problem. If you look at the picture, notice that the tips of the outer leaves are most affected. Wouldn't symptoms of excess light be most apparent on the leaf surfaces closest to the light?

In any case, I haven't seen any significant change in the plant's condition since the pick was posted.

What types of temp/humidity do Chirita tend to prefer? I haven't turned on the air conditioning, and hope not to have to. Temps have only occasionaly gotten over 80 so far this summer, and indoor humidity is typically around 40%-50%. I could probably rig up some sort of humidity tray to boost humidity.

Red leaves on chiritas is a known problem. But, I don't know what the cause is. It isn't too much light. Also, they don't need high humidity, or extra warm or cool conditions. For the most part chiritas are very tough. They don't need to be kept as evenly moist as AV's so generally are not wicked. Allowing the soil to dry just a bit between watering seems to help them. I grow them under lights and in window sills. I find they do well in both situations. They are also hardy here, but outdoors I have to watch for animals that eat their leaves--deer or squirrels?? Being succulent, they seem to thrive in relatively small pots with good indirect light. They don't need too much fertilizer, but a steady program will encourage flowering.
