If your a newish grower i would stick to a base feed. You can add rhizo and cannzym early on to get cuts nice and strong with a good root system...to be honest...unless your growroom is very dialed and really good at holding consistent temps..relative humidity...and co2...your bllom and boost additives will be negligible at best. Focus on your environment and dialing in your strains. Get a good base nutrient going..watching EC and pH. Focus on just them factors for a good 3 to 5 crop outs. Once your satisfied and got a good consistent system chugging along...THEN add some pricey bloom and boost additives. You will probably see real gains then.
