Only Miracle Grow Organic soils?

Hi, everyone. Here's a fast question. With ONLY Miracle grow organic soils and Sugar daddy, Micro grow and kool bloom good enough for planting? Or its better off to put some perlite and vermicille ? Thanks for your advicess

To be honest, you can get a pretty good yield on that kind of soil with no additives, but you will probably see Magnesium deficiency along the way like I did last time I tried it. A good preemptive cure is to mix in one TBSP of dolomite per gallon of soil. Trust me when I say it will save you a BUNCH of hassle with this soil if you add a touch of dolomite
