Plant in pic #1 is Aloe juvenna. Did you move it from darker spot into much more sunlight? Browning from the top sounds unusual to me. Older leaves - and sometimes leaves higher up - will brown and dry up, but not really from top down. Has there been and injury to the top?

The plant in pic #2 looks like Adromischus (cristatus) maculatus - sorry, original typo fixed...

well the aloe I bought from the nursery and it was inside - at home I put it outside in full sun - maybe it's too much, or must adjust. There has been no injury to the top - I have two and they are both doing the same thing

That sounds like it...many aloes (and many other succulents), if in full sun, will change color to reddish-brown. It will stay like that as long as it is in full sun. It could sunburn too, depends on how much sun it gets (easily happens if not acclimatized), and your general location.

I have never seen a speckled Andromischus like that. Very cool looking. I hope that's normal pigment. I usually see them bright green.

Can you post some photos of the browning aloe parts? People will be better able to judge if they see it for themselves.

Adromischus triflorus or maculata or more likely the correct identification for that spotted succulent. A crispatus is a fuzzy green plant.

Yes, I meant A. maculatus (I have it, and also have cristatus). Sorry...I fixed my original post, not sure why I typed cristatus...

I can see the tips of your Aloe juvenna are a getting tanned. Like Rina said, this is from the increased sunlight and is normal. It looks very healthy!

Not only will the plant turn a reddish brown when stressed - more sun, less water - it will return to green when no longer under stress.

This clump in the ground pictured during our sunny, but very dry winter -

And after I remembered to start watering it again after the summer rains passed -

Adromischus copperi it is, as mentioned it does have several leaf coloring variations, all copperi have the same long leaf with wide ends leaf shapes

Very much liking yours as well Kevin the OP has the'more common' ribbon shape on leaf tips.

got a pic last night - here is the small one turning brown

To my relatively untrained eye, that looks like a beautiful, plump, happy aloe with a healthy little tan. If it were mine, I'd keep doing what I'd been doing. Lovely plant.

Kevin, those are beautiful plants. I've never seen any like them.
