Would staggerd planting help?

My frost date is in mid October, but in mid September my plants start to look like carp, and the size, flavor and quality (large cores etc) of the fruit drops off so they aren't much better than store bought with still a month to go.

I'm sure that the cold nights have something to do with it, but I'm wondering if plant age and foliage fungal buildup is also a big culprit. Do you think that if I started a set of plants a month after the main plants that their first load of fruit would be higher quality than the old plants?

If you have the space and facility of a germinating space, why not give it a trial and report back?

My cold feame space (when I had it) was always overshadowed by squash vines of one kind or another when a second grow out might've been possible.

I once saw a video, where a tractor was hauling a wagon. The workers were jerking the determinate plants full of fruit, and throwing them in the wagon. A few yards behind them was another wagon with small transplants that a second crew was sticking into the new holes created by the harvest. With the right climate and varieties, it should work.
