What values are you trying to control exactly? It's possible that your negative(s) are not up to the task. You need a negative that is too contrasty even for platinotypes, as salt prints have a very long scale. And remember, you really need to "overprint" salt prints. If it looks a little too dark, it's probably about right. The print will lighten up during your processing (wash, tone, fix...). Good note taking and a consistent light source are key as well.
