The only nute I used for soil was foxfarms 6 part nutes. Worked awsome with big buds! As for hydro it's up to you. Many swear by different products and the one I chose was advanced nutrient sensi 2 part with foxfarm enhancements. Also I noticed you wanted to keep mothers with your e&f setup. I would suggest keeping mothers in dirt. If power goes out or a pump breaks then your genetics are safe.
