Nitrogen is a volatile element. One of the main reasons it is not included on a soil test is because the level is constantly changing.
The easiest thng to do is to not add any more nitrogen and plant leafy greens which can use the nitrogen.
As long as the greens grow robustly, you probably have a lot of nitrogen in the soil.
After you redo the bed, add more compost before planting your next crop. I would avoid planting root vegetables until the nitrogen levels have dropped otherwise you will get a lot of tops and not much roots.
You can test if the nitrogen levels have dropped by planting radishes. It is a short crop, if the levels have dropped sufficiently the radishes will form bulbs if not you see more top growth and not much roots.
One of my plots does have a lot of nitrogen, and the pH is acidic. Great for tomatoes, spinach, kale, chard and corn but not good for beets, daikon, or taro. I planted one crop of corn adding only blood meal as a slow release nitrogen and compost and got my usual 7 ft cornstalks with up to three ears on each plant. I added nothing to the next set of plantings and the height of the corn was cut by 1/3, so the nitrogen depleted fairly rapidly especially when a high nitrogen feeder crop like corn is planted.
Happy gardening in Hawaii. Gardens are where people grow.
