AN beneficial bacteria??

I am using up the last of my AN products, the nutrient calculator on their website says to use voodoo juice, Piranha, and [URL='http://www.advancednutrients.com/hydroponics/products/tarantula/tarantula_product_information.php']Tarantula for the first 2 weeks of flower to inoculate roots. Does anyone else or should I keep using more through the flower cycle?[/URL]
