Plants losing their leaves suddenly

[maryanne27]

I have quite a few live plants in my enclosure, and just recently most of them started dropping a lot of leaves. Three crotons (two separate species) and my creeping ficus are the main ones afflicted. The pathos, fern, and one other type of croton seem ok.

The room is air conditioned to keep it in the low 70s all the time (montane species here), I have an Arcadia UV light that I got in April, and the enclosure is misted regularly with a timer throughout the day. I havent changed anything since I moved everything to this larger enclosure about a month or so ago.

Is this something I should worry about? Obviously I don't want all my plants to die, but more importantly I don't want it to be something that could harm my chameleon. Any help or suggestions are appreciated!

Here is a pic if it helps. At first I thought maybe the crotons on the bottom didn't get enough light or water, but the ficus is right up there and having the same problem.

Too dim and the soil is too heavy/wet. The crotons want warmth and bright light.
