Just my 2˘ but it's the 4-18-38, use it for ground plants next year and you'll see a difference. I grow in perlite with it, epsom and CalNit and they grow fine so I know the media isn't as big of a deal as the fertilizer. I think growing in potting mix and using 4-18-38 produces a better harvest due to the uptake of some nutrients of the media.
