I too scorched a few cacti about a month ago. I kept reading a large number of my collection can take full sun so I thought I would give them full sun. Well just after about half a day I got the same results as yours. Very disheartening. I think the lack of air movement was the worse factor. I left ...

Yes, I pot them in very drainy soil, basically 90% grit. When I water them, water starts draining out of the hole almost immediately.
