“If your soil has too much nitrogen, you can get too much green and not enough produce. Other nutrients such as potassium and phosporous are great for getting flowers/produce in combination with sufficient nitrogen.”
OK, the Kentucky Wonders and the squash are in ground. Everything else is in potting soil mix. So, what about potting soil mix? Does it have in it what every food plant needs - the right amount of nitrogen, potassium and phosporous? This is getting more complicated.
I would think that the potting mix would be in general good enough to grow any veggie. You can check the bag to see what combo they have.
Beans are not too particular, so I think they’ll be ok. Keep in mind that Kentucky Wonder grown for dried beans will take about 100 days IIRC, so don’t sweat it.
Your squash is obviously doing well. When my vines got too long, I just pinched off the tip. I still got more than I could eat or use.
Potting soil like Miracle grow has everything for 6 months but I like to add soluble Miracle grow fertilizer once a week. I believe they recommend it. It can be confusing at first. Stick with it. If you can get a PhD you can learn gardening. Sometimes not enough nitrogen is the problem. My barley wasn’t going to seed and I realized I had quit fertilizing over the winter and we had been out of town and what not. I hit it once with the Miracle Grow fertilizer and in days it was putting out nice heads of barley seed. I had just gotten lazy over the winter. Your beans will produce, I am certain.
