Hi! I've never used advanced nutrients, but you definitely need to use the grow product with nitrogen, starting with half doses and increasing until the beginning of flowering, then decreasing again until the week before the flush, while you use the flowering products from the start of flowering (half dose) up to a full dose the week before the flush. Also, use the fertilizer with micronutrients, as it's very easy to have a micronutrient deficiency in hydro/aero :)
