Awesome OGRE !!!!!!! Those are trees. A great organic fert to use for feeding is Earth Juice. I have never burned a plant with it. Another idea, would be to mix in some bat guano(high in N) around the base of each plant. It would take 2-3 weeks to start breaking down for food. If you are not seeing any indication of lack of food, I would not add any. The soil might have more food than you think. Some sativas do not need as much food as your typical indica strains.
Those plants are a good selection for your hot and humid enviroment. When is your first chance of frost. Late November?
