As you can see, the sourdough starter was more than doubled in size on day 3, with "hooch" on the bottom. It also still smelled terrible. Hooch is a clear-to-dark-coloured liquid that can collect at the top or the bottom of your starter when it's hungry and needs a feeding. It's normal and not a sign it's gone bad or moldy. However, watch out for a pink or orange tint or streak, as this is actually a sign that your sourdough starter has gone bad and should be tossed (it's unlikely to happen unless you've left it out for weeks without feeding).
