There are a lot of organic fertilizers available. If you are planting in pots then just use fish emulsion and kelp. Most garden centers will carry a line of organic products.
If you are planting in ground. It is best to start by adding compost and manure in the fall to your bed. Organic requires that you constantly add compost for the carbon. Liquid fertilizers will provide faster releasing nutrients like nitrogen but the basics of organic gardening is to feed the soil and build up the soil web so it can feed the plants. A liquid diet primarily feeds the plants. If you are fertilizing just to feed the plants than why choose organic?
BTW unless you have a large enough soil volume in pots, there is probably not a large enough microbe population to support plants. You will be obligated to provide fertilizer like fish emulsion to support most vegetable growth to maturity. If you are supplying more than 10% of the nutrients through additional feeding like compost or manure tea, fish emulsion, kelp meal, etc, then the soil is not sustaining the plants, the fertilizer is.
Happy gardening in Hawaii. Gardens are where people grow.
