I keep the pH within ranges that plants can uptake nutrients and apply both mineral and trace mineral supplements in sufficient quantities. Azomite for instance which I apply to working compost and calcium magnesium supplements. Additionally I apply other supplements like organic acids (fulvic and humic acid) which aid in the transport.

I also remove all minerals from irrigation water with RO and use an engineered growing medium rather than growing in native soil. But it's organic (and alive with microbes), not hydroponic or anything like that.
