Change nutrients or keep the same?

Hi, im currently using the canna nutrients, boost, pk13/14 etc. Im looking to get more yields by using new systems, lights, shades etc and i was wondering as there are hunderds of nutrients available, what are the best ones for increasing yield?

increase your yield by getting better lights and vegging longer. As for nutes , everyone will have their own opinion .
