Here’s a link to, what I call, @YoBigdaddy’s Sativa Dirt. I've been hunting unicorns "Da Lat" - #98 by YoBigdaddy
The mix is high in mineral content, so it requires more time to “cook”, but it really seems to work well on the sativas. There’s no added N, except what’s contained in the various components.
I’ve been using a soiless mix, but I haven’t been happy with my results of late, so I’m switching back to dirt. 
Good luck with those my man.
