My cactus leaves have holes in them and turning brown. Don't know what's causing this. Plant is potted, indoors, indirect light, and about 4 ft tall, sprouting leaves and those longggg stems! Dont "see" any bugs; moved it in 2019 from fl, it was on a covered lanai and beautiful - even bloomed last year (and this was from a cutting); now living in southern NC, inside now. Can you tell me what the problem is; should it be moved elsewhere (have no shade outside to put in summer either), how to treat it? Don't want to lose it...lost a precious begonia last year - outgrowing itself in FL on lanai, but moved it to NC, died (was also indoors and indirect light). Thanks for your immediate help.
I would have to say that the new environment is against you, here! The Cereus will prefer hot temperatures. (They like it up in the 90's and 100's) They, also, really need that humidity to be happy, as well as full sun unless it is overly hot. Caring for these, indoors, will be quite tricky, as it may require extra humidity, heat, and light.

what is happening to this cactus, and how to fix? thanks
I have answered this in the original question, but I'll add this- I would hold off in between watering until the soil is completely dry down to about an inch, to two inches between watering. That looks to be damage from overwatering.
You may, also, want to treat with a fungicide: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
My night blooming cereus has put out stems with what looks like roots growing put from them. What do I do if anything? Do I cut and root them? Do I support them? What are they about?, it has never done this before. It used to live outdoors in Long Beach. Since moving to Stockton, where it is colder I brought it indoors for winter.
Those hairlike projections are just aerial roots that the cactus uses for climbing. You can ignore them.
My indoor night-blooming cereus bud has been developing for just over two weeks and is now a bit over 6 inches long. It has started curving towards the window. Does anyone have a good estimate on the amount of time left until it blossoms--if it doesn’t fall off! Assuming it does bloom, I want to be able to see it, and to have a (virtual) blossom party. Should I be able to turn the plant around so the bud is facing into the room, and if so when should I do that? It’s the first time I’ve had a bud that didn’t fall off, so I will appreciate any advice that I can get!
That will not be something that anyone can tell you. Flowering times will depend on the environment around the plant, and you will have to watch for signs of it loosening up before it opens. Once it starts to loosen, you will start watching it closely.

Thank you.. I have seen a few descriptions of when the bud is ready to pop, but not that one. It’s useful because it will be something I can recognize when it starts happening.
SO I HAVE HAD MY FLAT LEAFED NIGHT BLOOMING CEREUS FOR SEVERAL YEARS IT HAS SEVERAL LEAFS THAT ARE BROWN AND DRY AND CRISPY WHY?
Unfortunately, your photo did not come through. This can have many causes, and will usually need some form of treatment.
Most likely, it is a fungal/bacterial infection. Typically, this is caused by soil that does not have a chance to dry out between waterings, or overwatering.
The first step is to treat the infection. Depending on where the infection occurs on the leaf, exactly, and how it looks, exactly, it could have different pests.
Here are some articles that will help:

It started on the ends of a couple leaves. I just cut off the brown stuff but it is persisting on the end of the sprout now. The rest of the plant is doing great and I got 3 blooms last year.
Unfortunately, the plant is suffering from a bacterial/fungal infection.
Treatment will be a bactericide, or fungicide. These articles will help:

It will be necessary, to also correct the watering habits that lead to infection, and possibly the type of soil
Make sure that this is a very fast draining, gritty soil. Cactus mix with a little compost is ideal. Make sure that the mix dries out, almost completely to the bottom of the container, between waterings.

My NBC used to bloom regularly when we put it here on the right side of this south facing window years ago. About 5 mos ago, tried to give more some new nutrient richer potting soil, I now realize I probably damaged the roots by trying to loosen them w a screwdriver - big mistake. Now she is no longer blooming and some leaves are yellowing and spotting. I normally water only 1/wk and will give her a humidifier if her leafs look flacid. Any suggestions would be greatly appreciated, Thank You!
It is very hard to tell from these photos. Try facing the light source behind you so that it does not drown the picture out.
That growth is VERY stretched. This will indicate that the light source is not enough. I would supplement with a horticultural lamp.
Pruning may also be in order.
Depending on what fertilizer you used, and how much, I would say this is the problem. They do like rich, fast-draining soil, but it is best to feed them at half strength to see how it will respond to the fertilizer.
Pruning may also be in order.
