Dwc basic nutrient line, Plus what other nutrients have you been successful with?

Ok so what other nutrients besides the basic grow, bloom, etc. would you recommend using and why? I’m about to go with the DWC method and attempt a SCROG setup. While I was looking up the proper nutrients I kept reading all these extras like cal mag and several others that I can’t remember. I was just wondering what would be the best route. If anyone can shed some light on this it would be greatly appreciated. If you can please explain what and why you use what you use and how you have been successful with it. Any noticeable difference before and after. Also anything that I should stay away from. Thanks in advance! Grow big everyone!
