Many succulents will change color with more sunlight, so that shouldn't be a problem. However, squishy doesn't sound good. Do you have photo of 'squishy' leave and/or cut one that you say is not green on inside?
What kind of soil was it in? How often did you water it before?

Also were you pouring water onto the crown of the plant? Or around it? Water sitting in the crown will rot your Haw quickly. I've killed many this way.

It was in Miracle Gro cactus soil, with a lot of added perlite. I was watering it every two weeks, which I eventually realized might be too often. I was trying to water around it rather than on it. I'm about to go on a hiking trip with my family, but here's a picture of a leaf. I hope I didn't just do unnecessary surgery- it's a really sad looking plant now that everything squishy is gone.

I'm going to let the wounds callus over for about a week, then repot. Most of the top ended up coming off, so I'm hoping it will make good use of the growing season. I've read that fertilizing directly after repotting for most plants is a bad idea. How long would you wait?

Cleo,
I think your plant was just adjusting to the change. If that is a haworthia or a hybrid thereof, then it will just be approaching the end of its growing season. Haworthias grow in spring and autumn. In the hottest part of summer, they go dormant. They also slow down in the coldest part of the winter. Most of my haworthias are in pure pumice but I also have some in about 40 percent potting soil and 60 percent pumice (I just never got around to repotting them). In zone 7, I water weekly during spring (March to mid-June) and in July, I stop watering. I resume watering in September and slow down on watering around November, when they are brought indoors. Even in winter I water maybe every two to three weeks, I really dont worry too much.

The kind you have is one of the sturdier ones (might even been an aloe hybrid?) But as long as its out of the pot, you might as well mix up a better kind of potting mix. I strongly recommend more perlite than soil in your mix. You can water it as soon as you have it potted up---the best way is to water around the plant, closest of the walls of the pot and away from the rosette. If your nights are still going below 16C, you can probably still water it weekly. Keep it in bright shade for the moment though, and probably throughout summer. You don't need to fertilize it until autumn, it won't need it until it has recovered fully from being disturbed.

Hope this helps

Repotting sounds like a good idea at this point, although from the pictures I don't think it's in too much of a distress. Haworthia loses its green for various reasons, I recently posted about this issue too and after some adjustments in lighting and watering they're already doing better. Softening leaves, on the other hand, is usually not a good sign though. If it is getting less water and more sunlight like you said, rotting shouldn't be the problem but still, repot it and keep it at a cool/shady place for a week or two and see how it does
