So, I'm growing a Big Max pumpkin in a 4x8 bed. Everything was going just fine, one viable pumpkin started growing. Things were looking good.
All of the sudden, the vine itself just stopped growing, at all. Its been like that for several weeks now. I water almost daily (live south of Denver, Colorado. Its gotten dry). I've fertilized with Miracle Grow twice during this same timeframe. I do not really see any obvious disease or bugs. Its just not growing at all. Leaves that were small and had just unfolded prior to this period are exactly the same size, but still green. The plant itself looks fine to my (noob) eyes, just not growing. The pumpkin has either stopped getting bigger or is growing very slowly.
I'll include some pictures of the plant:
This is the tip of the main vine:
Thank you for any help!
