Tropical Fruit Kelp Foliar Spray Schedule

[Tropicalgrower89]

Hello fellow fruit enthusiasts. It has been a while since I've been here. I had just applied a kelp foliar spray with a bit of fulvic acid mixed into it to my tropical fruit trees. According to the Kelp I bought (Clean Kelp from Bloom City), I should use the product every 4 to 7 days for plants. But for my fruit trees (mango, mamey sapote, sweetsop, sapodilla, bananas) how often should I spray them? 

Thank you for your help
