nutrient/fert question

I saw in my local hardware store liquid organic fertilizer

it suggests foliar feeding and i was wondering if i could use that liquid organic fert as normal fertilizer where i water my roots with it? (diluted/etc of course)

You can use any nute you want, the question is will MJ like it?

i was actually thinking of that too.

npk is npk afterall. just curious if there are other opinions regarding this
