Giant Pumpkin Growth

For the last three days my pumpkin is adding about 3 1/2-4 inches per day in circumference growth.  Prior to that it was putting on a very consistent 5 inches per day.  The pumpkin is 25 days old now so at this point of the season the pumpkin should be putting on about 4-4 1/2 inches per day in order for it to hit 1,200 pounds at the end of the season.  Not that the charts mean much, but my pumpkin prior to a few days ago had been consistently on the charts for hitting 1,200 pounds at the end of the season.  Because of the current growth pattern I decided to give the plant around 1/8 cup of Neptune's Fish & Seaweed (2-3-1).  I don't like to give the plant much if any fertilizer when it is around the rapid growth stage (day 28 to day 40) for fear of blowing a pumpkin up but it seemed like a reasonable risk looking at the future weather forecast and how the plant has been growing.  Slow and steady wins the race but pushing the pumpkin a little from time to time isn't a bad idea either.
