Hello, so just four days ago I got two African Violet plants four days ago. (In the pic they are inside because it is dark, during the day they are on a windowsill). I've been worried about their health. On the violet/white flower petals, some of the petals have turned brown and are shriveling up. Also, both plants have these white streaks on the top of the leaves. On the pink one, one leaf has an inch-long crack in them, one leaf's edge is curling downward with what looks like a crack forming, and another leaf's edge is turning brown. It did not look like this when I got it. In fact, I just saw all of this first today.
