You may have to consider the timing when you repot them..I usually try to do my repot in early Spring of my succulents, if it can wait. Or early Fall is also good, it just came from very hot temps and by Fall, temps are cooling down slowly, still giving time for new transplants to grow roots before colder weather sets in.
In our area since it is just so bone dry, I have to spray the semps every morning, and it seems to work, seeing offsets and more color variation, but the heat of the sun has prompted some to bolt early. So it seems, got to somehow help this plants keep cool, after all they are more of alpine succulents.
