Hi. I take care of several ag's and some are troubling me. Most varieties are Silver Queen or Emeral Beauty. The problem is they are either very happy or very unhappy. Some continue to have yellow leaves every week. I have adjusted the water, but, that seems to lead to spots on the leaves. I am fearful of adding too much water as some have rotted on me, and that is not pleasant. They are all 14" ag's in at least 24" pots. What am I doing wrong here?

My solloum are growing but they are not standing up. The edges of the older leaves are brown. I water them very carefully. They are in 14" pots in very low light. Some people say these plants are easy to grow, but I either over water or underwater. Is there a way to tell how much to give them by the look of the plant? I have 12 plants and do not want to kill them.

Your advice would be greatly appreciated.

Diana
