Karen: 50/50 grit and soil mix, yes there's holes, I water once a week (1-2 big tbsps of water)

They look like they are thirsty and beginning to shrivel from lack of water.

I raise echies in Texas and it gets very hot here. I water once a week also , but I give them a good drink. I slop it in till it is coming out of the holes. Also they do get a break from the sun. They are in shade half the day . When the temps com out of the 90's ( 30's), I will give them a bit more sun.

I agree with Breton - so thirrrsty. You will want to give them a good soak in a bowl or pot or something for a few minutes. Then drain off the excess water (I place mine on a folded towel for a bit to absorb any remaining drippies before returning to their sills.)

Thank you all for the comments! I'm gonna adjust their watering right now!!

Good luck! By tomorrow they should be plumped right back up. Let soil dry before watering again.
