hydro nutes in soil?

I'm a hydro grower, but I decided to switch my mother plants over to soil. Can I use hydro nutes (specifically GH 3-part) in soil? If I feed weekly, what mixing formula would I use for feeding soil mother plants with General Hydroponics nutrients? Would it be more dilute or more concentrated than the hydro fertilizer solution ?

These soil mothers will never see the flowering room and they are relatively few compared to the hydro plants. Could I just get away with using hydro nutes so I don't have to spend more money at the grow store? In a month or so I will be harvesting and will have money to buy proper soil nutes.

Appreciate the help. I searched all over the place and couldn't find an answer... but I doubt I'm the first person to ask this question.

depends on the nutes, my flora nova says right on the bottle that you can. However, I have never done this and it seems very easy to over nute..
