Just use fox farm ocean forest. Use it with big bloom and water for the veg stage, unless u plan on running a longer veg time, then add in some grow big later on. This soil has a good amount of N so u won't need to add much, if any. And for flower, just big bloom and tiger bloom. No need to add a bunch of other stuff. I think that is where a lot of people run into problems. They seem to think adding more stuff will only make it better, which is not the case. As the company fox farm says themselves "less is better"
