The holes in the leaves could be flea beetles.
I usually do get spider mites at this time of the year. They are not easy to see, but the underside of the leaf will show bronzing and upper surface of the leaf will look like something has been scratching it. The webbing comes later. The spider mites show up in hot dusty weather. There are natural controls that will be killed by sprays. Hosing off the foliage with water dislodges them.
Healthy plants are poor targets for pests and disease. Keep plants well watered and fed. Hose dust of leaves and spray jets of water under leaves to dislodge pests.
Plant a diversified landscape and plants that provide nectar and attract beneficial insects like ladybugs, hover flies and parasitic wasps. Plants in the parsley family, dill, fennel, parsley, caraway with umbrel flowers. Disc flowers like sunflowers, marigolds, zinnia, calendula, cosmos and others also attract beneficial insects. Plants like sweet alyssum, false heather, etc provide nectar. A shallow dish of water filled with pebbles provide water. Pesticides will kill beneficial insects so you will need to give the beneficial insects a chance to control pests and avoid spraying. Some damage needs to tolerated.
Happy gardening in Hawaii. Gardens are where people grow.
