Here is a reply , from Mike Orzolek @Penn State University.
regarding my soil test results. Some information here about Epsom salt.
Hope it helps a little.

Marvin,
After looking at your soil test results, there is no question that you have
more than ample supplies of phosphorus, potassium, and calcium. These
elements being excessive of itself is not a problem since plant toxicity
has not been found in the field with any of these elements. However, what
is more critical is the balance between potassium, magnesium and calcium.
Plants generally will preferentially take up potassium 1st, magnesium 2nd,
and calcium 3rd. With a very high potassium level and somewhat low
magnesium level, as the giant pumpkin plant gets larger, you may see
visible signs of magnesium defeciency in the plant - yellowing between the
veins of older leaves. With this in mind, I would recommend that you apply
foliar applications of Epsom salt (magnesium sulfate) - 2 ounces per gallon
of water and apply to the pumpkin plants once a week.
High phosphorus levels can reduce nitrogen uptake in the plant, but if your
plants appear green, I wouldn't worry about the high phosphorus levels.
If you have any additional questions, please contact me again at your
convenience. Good Luck!
Mike Orzolek
