Do NOT throw that paper. You did not size incorrectly. And, even if you did use too little sizing as you may think, you can always use one more coating if desired. However, I think two coatings errs on too much sizing.
Yellowing can definitely be from too much gelatin as Loris says. It can also be from certain hardeners on alkaline paper.
I cannot see my gelatin sizing once it is soaked into the paper. It is very hard to see. I have to actually label which side I size to see it.
Sometimes I can see a bead of glossy gelatin along the edge of the paper.
I do not use two coats of gelatin when I size, only one. Otherwise it can get too slick and flaking can occur, but some do use two coats.
I have also been using Gamblin PVA sizing 1+2 water on Fabriano Artistico Extra White and it does adequately well. That, too, is very hard to see on the paper, although it is easier to feel it. It feels a bit smooth and acrylic-y.
