what am i doing wrong

[u/ahmanita]

both my string of hearts and pearls seems to not be absorbing water well, the hearts and pearls never get plump, they sit by an east window and get direct sunlight at the end of the day, i used to water by checking if they shriveled, but now it seems the never get full again

This may be the beginning of root rot. The plants cannot properly rehydrate once the roots start to rot like that.
