I have these seedlings and I want to grow this the right way

I have 8 autoflowers 3 blue dream, 2 ak47, 3 lemon haze. I have them in soil. I always have the fox farm trio but I’m only planning to use it on 4 of my plants but I have some trouble using it sometime. If anybody can help me out and putting me on the right track to growing the best buds that will be very helpful. Ak47 is 1 week old and the rest are a couple days.
