African Violet Help

Hi all! I repotted two of my African Violets into a soil mix specifically made for them about two weeks ago and they’ve just been struggling ever since. I moved last week and have been moving them around every few days to see if a lighting change would help, it unfortunately has not.

I was wondering if anyone would have any advice or suggestions on what I could do to stop them from completely dying. As shown in the first picture, their leaves are shriveling up from closer to the plant body. I’ve also only been bottom watering them, so I’m hoping it’s not crown rot.

Thanks!
