I just got my new Green Star juicer. Haha, my mom says it looks like a robot. Anyway, It does a good job with apples and carrots so far, but the spinach gave me A LOT of foam. Do I have to adjust the knob a certain way? I havn't used the fruit knob yet. It gave me a lot of spinach flavor though, but I'd prefer no or minimal foam. I know a lot of people have said that there is less foam with the GS when it does greens. Am I doing something wrong here?
