Once you've chopped the pumpkin, sweet potatoes, and apples, add them to a large bowl with the sea salt, garlic powder, onion powder, turmeric powder, ginger powder, and cinnamon powder and stir well to coat evenly.
Add the bone broth, onion, and fresh herbs to the slow cooker.
Transfer the vegetables and apples to the slow cooker and secure with the lid.
Cook on high for 6 hours. You can give the vegetables a quick stir midway through the cook. The bone broth is not meant to cover the vegetables, the steam will ensure that it cooks through.
Once your vegetables are cooked through, add your coconut milk to the pot and give it a good stir.
Transfer the mixture into the food processor and blend in batches until you reach your desired consistency. OR use a stick blender to blend into a soup.
