Hempy nutes

Im going to do a hempy bucket grow with a few bag seed just for practice

My question is Rather than use the good nutes, could i mix up some MG in a weak
solution and use that?

I never done this so Im not trying to do anything but learn and if i kill some shawg

seed no biggie.

thanks
