Browning succulent

[Thornn]

Hey,
I purchased the attached succulents from a local resident who left them out for sale.

Recently 2 have started to brown slightly. I can’t work out if it’s sunburn or something else because when I google Succulent going brown (and/or dry) it comes up with it being sunburn, or over/underwatered.

I have tried watering thoroughly, then letting it dry for longer.

Has anyone had this before, and how can I resolve it?

The small plant (Sedum) with lots of little leaves has just finished flowering, and the old flowers at the 5 o'clock position on the bottom photo are drying up and going brown. So that's nothing to worry about.
Your other plant had maybe got slightly dry and lost a few of its older leaves. Again, nothing to worry about. Give it a thorough watering and it should grow some new ones. I can't really see any problems - plants may get a bit dry in summer and lose a few leaves, but that's normal, unless they are all watered very frequently or rained on continuously (and that may not be a good thing).

Phew thanks! I was worried because the back one looks more like it’s wilting and falling over but I water them all once a week. I have fish so I am planning to water next with some of the tank water (hopefully it won’t kill them further but give them nutrients!) maybe I will try specifically aim for the back incase the other plants are stealing his water!
