I rescued a schefflera from wal mart, brought it home and repotted it. It was has growing leaps and bounds but the last week all the new leaves have these brown spots on them, the stem is also getting the freckles, the split leave philly that sets beside it has also developed the same brown spots but it is slowly dyine. Does anyone know what this is, will it affect my other plants around it, what can i do to help my ailing missy. thanks
