You are in zone 8. The higher the number, the hotter the region. Try to plant according to your zone. Instructions are on the back of a seed packet. I am speculating that you planted too late for your zone and then didn’t water them as much as they needed. They were too young and delicate to tolerate the hot summer sun and lack of water didn’t help. Raised beds tend to dry out quickly and need more water. Your soil sounds fine as does your fertilizer. I would till the soil around your plants once a week. You probably don’t have worms and tilling the dirt helps aeration of the soil, which worms do. If all of your plants are dying, then I assume that bugs are not the reason as certain bugs like only certain plants.

Next year, plant in stages. Cold weather crops that can take a light frost can be grown early, like lettuce, spinach, kale, broccoli and cauliflower. As soon as the threat of frost is gone (yes, watch weather forecasts very closely), then plant the rest of your garden.

I hope that helps.

PS - if plants are really healthy but don’t produce, then there are two reasons that would cause this. Sometimes too much fertilizer will do this as the plant figures out that reproducing isn’t important as it’s life is just awesome. The other reason is lack of pollination. Consider putting a honeybee hive close by to help or you pollinating them yourself with a wet Q-Tip.

And one last thing. Plant have a consciousness. Don’t be afraid to lovingly talk to them from time to time.
