Hi KJ, you want to discard starter with each feeding. As long as you are feeding with equal parts water and flour you should be on the right track. 1 part starter to 1 part water to 1 part flour. I will link below our complete sourdough guide. We are always happy to troubleshoot with you on our Baker's Hotline if you have any other specific questions. We can be reached at (855) 371-2253 (BAKE). https://www.kingarthurbaking.com/learn/guides/sourdough Happy Baking!
