A few questions. What is the environment in the room that it is in? Is it hot or cold? Is the humidity really low? Is it by any chance near a heat register or a drafty window? Does it get direct sun, filtered sun or no sun?
As to watering, if you stick your finger into the soil about an inch deep is the soil is it wet or damp? Is the soil cold?

WillC said:A one-stem-per-pot rule is nonsense!
Your plant is reacting to the roots being disturbed when you separated on of the plants and repotted. When repotting and dividing, it is almost impossible to avoid damageing the tiny root hairs that do most of the work. Other things that can easlily go wrong when repotting are using inapproriate potting mix and a pot that has no drain hole.
Unfortunately, the symptoms shown are generic and your Marginata may be reacting to any or all of these factors and also inadequate light and improper watering.
I'm sorry you read that information on line.
