It looks like nutritional deficiencies. Tomatoes are heavy feeders, they will need to be supplemented weekly with some kind of water soluble fertilizer or fish emulsion. They are big enough to pot up.
If these are indeterminate containers you will need to pot up anywhere between 25-65 liter containers. 25 liters for a small determinate tomato that will not grow more than 5 ft and 65 liters for tomatoes that are taller than 6 ft.
I use one part peat moss, one part perlite. You can throw in a couple of handfuls of vermicast. 1/2 cup of a general purpose fertilizer for vegetables should be mixed in with the potting soil before you plant. Supplement weekly with a water soluble fertilizer or monthly with a slow Nitrogen granular fertilizer. Unless you are using pots bigger than 27 gallons, it will be difficult to get your tomatoes to grow organically. Organic fertilizer requires soil organisms to convert it into minerals that the plants can absorb. There is not a big enough population in small pots to feed both the organisms and the plant. Be careful with indoor plants, they are easy to over water if they have inadequate drainage or are allowed to sit in water for a long time. Overwatering is a common reason for the plant leaves to turn yellow and fall.
Happy gardening in Hawaii. Gardens are where people grow.
