I started to notice a lot of brown spots on the pebble from areas that leaves are not getting picked up quickly enough. I tried brushing the areas and that didn’t work. How do I get rid of these stains?

Organic staining should eventually lighten and go away with a slightly elevated FC level. Refer to the FC/CYA Levels to ensure your are first in the appropriate (ideal) FC zone, then consider raising it by an additional 3-4 ppm for a few days. If the stains still don't go away, consider rubbing a stain with a chlorine tab or sprinkle some cal-hypo granules on it as a test just to ensure it is indeed organic.
CYA is out of range. Waiting for calcium increaser to increase the CYA. I also recently started adding liquid chlorine as the temp is too low for the SWG to make chlorine. Do I just scrub the brown spots off after getting CYA back to the appropriate level?

Calcium increaser has no effect on stabilizer/CYA.
If you need more stabilizer/CYA then get it dissolving in your pool.
If the brown spots scrub off then do it.
Low CYA does not mean you should let your FC get low. Add more FC as needed until you get CYA in the water.
Increased the CYA and FC to proper levels. Still have the brown spots that are likely from leaves sitting on the pebble. I have tried scrubbing them off but they wont come off. What do you suggest?

What levels are that?
Run your FC hit at half SLAM level, and organic stains should bleach out over time.

Brown stains are back at FC is at 5. I’m seeing many of the stains on various areas. Brushing doesn’t help.

What is your CYA at?
That will drive your FC requirement, and likely the same advice as above. Did the chlorine fix the stains last year?

The leaf stains are common and will GRADUALLY come off completely if you keep your chlorine elevated by about 50% above normal levels.
CYA is a bit high at 70. Guess I miscalculated when adding it. Should I bring CYA down?
Brown stains that are on the wall of the pebble. Two are directly next to lights. Not sure why.

Can you post pictures?
The lights is a clue. Take some vitamin C tablets, put them in a sock and rub the sock over the stains, see if they lift. Particularly by the lights.

The pictures are not coming out very clearly. There are brown lines appearing under the lights in several areas of the pool. I will try the vitamin c. What do you think is going on?

How do I fix this and what is the reason this happening? Should I check TA again?

Diagnose first. Try the vitamin c tablets. Don't fix anything until you know what it is. We don't know what it is. This the first step in the diagnosis.
No need to test TA, has nothing to do with it.
Also post some pics of the stains.

Slightly worked with the tablets. Need a lot more tablets or something stronger. Some stains came out better than others. But instead of a dark brown, the color is lighter. What do you suggest? I found a chemical called A+ stain remover as well as a product from Chlorox to remove metals.
Pictures help.
The stains didn't get there overnight. Expecting them to be gone overnight is not realistic.
So, if the stains lightened with the tablets, that indicates they are iron. An ascorbic Acid treatment would be my next step
Stay away from "Magic bullets". Do the ascorbic acid treatment and report your results

I have no idea what "A+ stain remover" is nor do I have any idea what the Chlorox stain remover is.
