Is it just those two leaves?

@laticauda yeah it's just those two

If this were my plant, I'd get a very clean and sharp knife and cut those leaves off. Don't water til the wounds have healed.

Just far enough back to be sure it hasn't already spread. Try to save as much leaf as you can. That's what it'll use to sustain itself when recovering from the pruning.

EDIT: I would also take it out of its soil and let the roots dry. Then reassess once things have healed up. That will give you time to collect the necessary ingredients to pot this up. I don't think you need to break it up though.

Also, I'm not sure, but if in had to guess, I'd say this is a gasteraloe?

@laticauda yes I believe its a gasteraloe.

What do you think the cause of this was, so I can try to keep from it happening again... overwatering? too much sunlight?

Did you try to wipe the black spots off of the plant? It may rub off easily with a damp Q-tip or paper towel. You can also try wiping with a swab in rubbing alcohol.

i just tried that and it didn't wipe off and I realized that the leaves are also squishier than normal..

If it doesn't wipe off, then it may be a sign of rot. It is hard to tell what kind of soil the plants are in, but it looks pretty dark so I would guess it is a heavy peat-based soil. This kind of soil can retain too much water. Aloes like a free draining soil. You can accomplish that by adding 50% perlite to the soil. This will also help you avoid accidentally over-watering the plant.

Are those the only squishy leaves? They don't look that bad (squishy) in the picture, but that can be deceiving. I would check the soil and probably un-pot the plants to check the roots. Rot can spread rapidly, so fingers crossed that is not the problem.

You have a nice pot of plants. If you do un-pot them, it would be the perfect time to divide them if that is what you'd like to do. Warning - you will soon be addicted and have numerous pots of succulents!

Yes those are the only squishy ones. So should I just cut off those and repot the rest (in the new soil)?

haha this gives me a perfect excuse to have a bunch of new succulents in my house!

Yes, it appears as mildew but without cultures you'll never know for sure. Cut those leaves off and repot. Don't water til you see new growth. Unless you see it before those leaves had had a chance to callous over.

Get as much of the old stuff off as you can. You can probably use a hose, if you do this, I recommend letting the roots dry before reporting in the new mix to prevent this problem from recurring.

Re: more sun, less water should keep you set. I don't know about gasteraloe because I don't have any gasteraloe so don't know if they are more sensitive to the sun. But the color looked good, it was just too wet, probably overnight.

Okay thank you for the help!!

Take pictures of your progress! Just in case you have any questions.

Oh, and getting those leaves off ASAP and throwing them in the garbage, not to be composted, JIC.

Good advice from laticauda. All of my Aloes and Gasteria are in full sun, but I only have one Gasteraloe, Green Ice. That plant does not like being in the full sun in SW Florida. It looks much nicer in bright, diffused light.

If you move your plant outside into full sun, do it incrementally so it gets used to the direct light without burning. Sort of like getting a suntan, increase exposure over time. And if you see the plant is not liking it, you can pull it back before it gets fried. (This is advice that I should follow, being a fair skinned blonde! But of course I burn all the time because I don't follow my own advice!)

I did have it directly by my window but I had the shade pulled up so it got direct light (assuming that was what it needed) but I guess not! Now I have a screen in front of it so the light is much more diffused

How is the patient?

Hopefully it's doing well!

I am not sure of it being a Gasteraloe though. It does have distichous leaves, but I find this to be a common trait for younger plants. Here is an example of two Aloes (one is a that look quite different, depending on age:

My plants have similar white spots, but only on new growth. It looks like your hybrid has quite a bit of Aloe vera in it, if I were to guess.

Be sure to avoid too much moisture, which is what caused this to happen in the first place. :)

Once you can stick your whole finger down and feel that the soil is not moist anymore (sometimes it seems wet, but it's really just cool, so you actually have to rub your fingers together and ask yourself "do I feel water or crumbly dryness" and if it's crumbly dryness, then water thoroughly. Let all water run out of the bottom and just give it a good rinsing until you see water rushing out the holes. Lift the container. Does it feel like it absorbed enough water? Maybe you need to wait a few minutes and soak again, but this only applies when it needs it.

I have another problem, I would like your recommendations please
