Don't listen to these people suggesting hydro nutes for your soil. If you're actually growing in soil, use nutrients meant for soil. Jacks classic or miracle grow with a limestone amended soil is is what you should be using for soil.
If you want to use hydro nutes, use an inert media. Don't use lucas formula, especially in soil.
Nutrients meant for soil will provide the majority of N as urea and ammonium, while nutrients meant for hydro will provide the majority of N as nitrate. It will tell you this on the back. Soil based nutrients usually lack calcium, so your soil needs to have lime mixed in before you start growing.
