Do we need replastering?

First time to try posting with pics and didn't get the text in.....these brown stains are all over the pool and I've tried heavy chlorine and ascorbic acid on them with no effect. The previous owner last year said the pool needed replastering. Right? I don't know how old the pool is but what would have caused this kind of discoloration? Been practicing water balancing learned here during this year and can't tell if it's getting worse but I don't think so. Any thoughts appreciated.

If you want to check for stains, get the Jacks Magic Stain Kit.
Are the areas rough? Do they feel like plaster or has the plaster been worn off and you are seeing gunite?

The plaster is very rough in general, like sandpaper, but not more where the discoloration is. I can't tell if I'm seeing through to gunite or not.

If the pool is not leaking you don’t need to replaster.
Roughness can be scale.
Take some 80/100 grit wet/dry sandpaper and see how things feel after you put some elbow grease into an area.
Replastering is the nuclear option if you don’t want to put effort into clearing the stains and smoothing the scale.

I sincerely appreciate the suggestion, and were I young, energetic, and had a pool less than 9' deep I might try this, but since none of the above are true the nuclear option is much more attractive. Cheers.

I get this question a lot when inspecting pools. I always say that it is a spectrum and up to the individual - some people will be fine with a rough stained surface as long as it is not leaking, some people want it redone as soon as it is not perfect, most people fall somewhere in the middle.
Get some prices, and see if you feel like it is worth doing. If not, there might be some cheaper stopgap methods you could use to address whatever you don't like about the surface. Or just live with the patina and keep the water balanced.

You can most likely get rid of the staining with a acid wash but that won't help the roughness.
I've ordered a Jack's Magic Kit to try next week. Assuming the discoloration is staining of some kind will it come through new plaster - pebbletec-if the pool is replastered? Will the old plaster need to removed?
The staining will not come through to the new plaster BUT you DO need to remove the old plaster for the best plaster job. The key to a plaster job lasting a good, long time is how it is started up and how it is cared for down the road.
To me, the stains look like “dirty scale” where scale forms in a layer combined with or over top of the general dust & dirt in the pool. A chip out and re-plaster would of course fix the stains issue, as well as roughness and give you a nice, new finish. An acid wash might also fix the stains and get you a few more years of life out of the old plaster. What to do depends on what you’re trying to accomplish. Either way, for a great result, the workmanship and experience of the folks doing it is very important.
