You could switch over anytime now. Sometimes the leaves of the plant will tell you when it's time to switch. Parts of the leaves will start to yellow as the pumpkin's need for potassium starts to pull it from other parts of the plant. And if you still think you need to get more growth out of your plant then don't vary the balance of your mix by much. That is, you could try a foliar application of something like Miracle-Gro's water soluble tomato plant food, which has a NPK number of 18-18-21. Also seaweed will often have a fair amount of potassium in it and so keep using it. Oh! And let us know what your 30 day circumference measurements ended up to be will you?
