It actually looks I have a couple of older leaves that have a similar looking issue that some of Steve's plants have.... This is an old photo though, so I'd have to go look and see if it is still happening. No clue how that happened. Certainly not sun related as this has always lived under at least 50% shade cloth if not more shade.
This can go really dark, almost black in coloration.

I am really bad at keeping an eye on my Haworthias, not sure why... maybe because generally as long as I water them and do not give them too much sun, they tend to be OK, not great, I definitely have pots with significant die back, but OK in the sense that there are enough offsets to keep them going.

Thanks for sharing the koelmaniorum. I have seen it mentioned in other hybrids but never seen one for sale anywhere in the UK or EU. That is a nice big plant. Must be fairly old? I too love the texture of the leaves. I was going to ask how you keep haworthia in a very hot climate but you answered that already to some degree. I assume the shade tolerance in nature comes from the fact they are either submerged completely (like the windowed types) or growing underneath other plants for protection. Do you see the respiration problem you get on aloes with the higher nighttime temps? I seemed to have stopped the leaf problem for now . Not really sure how. I have switched off one LED light on each shelf (to try to simulate winter) and increased air movement a bit
