Yeah the Grow, Bloom and Top max will get you from start to finish. You can add the others but they aren't essential. Good to have some calmag if you need it. I've never really needed it but have it on standby now. I chose light mix as I'd read all mix can be a little hot for seedlings and autos. Some people use it without dramas though. I like the light mix as it gets you through the first week or two and then I'm in control of what the plants are getting.
