Installing wood stairs to bowed stringers problem

I recently purchased some hardwood floor and bullnoses to install on my existing stairs. I removed the carpet and cut off old bullnoses. I bought a stair jig to measure the not-perfect right angles for each stringer. However, what I realized immediately after putting the jig in, is that my stringers cup or bow out, meaning they are not flat with respect to the new tread I would be putting in. I have no idea how to fix this or what the proper solution would be? The cup is pretty bad in some areas, and caulking wouldn't look good. Thanks in advance.

Maybe a 4 1/2" grinder and a sanding flap disk would help you make quick work out of them... you want all the stringers to match.

Really would be better if you remove the old treads and installed new solid treads.
Got a picture so we can see how bad they are?
100% sure the skirts are tight to the wall?

Huh? Thought he said the stringer was bowed, and the old treads were gone?

Bowed components

If the stringer is bowed, use construction adhesive and scarf on 2 straight boards, one on each side and use very large C Clamps to draw them together and then screw though the scarf, stringer, and scarf. I recommend that if there is any brittleness or rot that you be sure to replace those parts. If possible putting in stringers would be better in the long run.
