Where were they for 2 weeks? - outside, inside, full sun, no sun?

Last plant needs more light - not strong sunlight, but good light.

It helps if you describe more about conditions they are in...and your general location.

I think "helpmeknow" is past help, "gettingcurvy" looks like it needs more sun, and "overallgood" needs more bright light. What kind of mix are they potted in?

I am crying. In the original mix they came with. They have been ok with water but then my hubby got in charge when I was away. Can I use the leaves of "helpmenow" to propagate/regrow?

Rina and S, All of them were on a fire mantel 9 feet from 3 windows. They have been there for about 6 months with no issue. Temp in the room is 71F constantly during the year. The one that historically have showed need for help was overallgood because the spikes were not sturdy and firmed.

9' from the window is way too far for succulents; even 1' from the window is too far. doubt very much there were OK - you may think they were, but that location is too dark. You can tell by such sickly, light green color of #2.

'helpmenow' is goner. leaves are too sick for propagating or anything. There is good chance that it is all rotten thru - stem and leaves. Perhaps it was watered too much while you were away? If you hold them between your fingers, I would bet they feel soft-squishy, and if you move the fingers (like rubbing it), they will be mushy.

I would add lots of sifted (coarse) perlite to the mix - min. 50% of total amount - to improve drainage. Also make sure there are drainage holes in pots. Slowly expose plants to more light - #2 should be in sunlight, #3 in bright light.

Husband did not water at all as per my posts. Water is dry when I water but nobody watered for 2 weeks. Helpmenow was looking good on July 31st. thank you all for helping.
