A Little Fox Farms Organic Big Bloom for the Pumpkin Plants

Today I gave the pumpkin plants some foliar and drench Big Bloom with their water.  It is a very mild organic fertilizer.  Less than 1% of NPK.  The plants are growing, although not terribly fast and I'm not sure why.  I'm not overly concerned about it at this point, but I would have expected the vines to be down by now, but they are not.  Both plants however have very thick stumps so that often keeps the vines up in the air longer.
