cast iron plant
 

I purchased some cast iron plants on ebay.
Planted a 1/3 in a pot get afternoon light, planted another 1/3 in a pot
gets morning light, the last 1/3 is still sitting in some water.
The plants roots were really dry and I sat them in water for about 2 weeks.
The potted plants two of the leaves are turning yellow. Does this mean too
much or too little water? Or is this a light problem?
