I have a gynura aurantiaca in my terrarium. The soil is coco-peat (bed-a-beast) with added fertilizer. I read that this plant needs high light so I put it right under my heat lamp (50 Watt, made for reptiles). the humidity is about 75-80% and the temperature is about the same (75-80 oF)
I water it lightly every day on account of the screen top. it was doing great but now the leaves are drooping and then wilting, finnaly falling off. It has leaf 'nubs' on the stem that seem to be growing, but very slowly.

The lighting is one 50 watt heat lamp desinged for reptiles and one Exo-Terra 5.0 lamp. Plus the cage is by an east-facing window. I have one green anole, one green treefrog, one gray treefrog, about five cricket frogs (VERY small) and one baby toad in the tank. Can someone help me with this problem?
