I grow in soil and I go: water, feed, feed, water. But what works for me might not work for you, my advice is to listen to your plant it will show you signs to let you know if its getting to much nutes or not enough, if its not showing either deficancy or toxicity then what your doing is working. Its best to start with low doses of nutes and work your way up. But again it depends on how your growing as hydro systems and soil have very different needs
