I'm going to be doing an rdwc grow using the General Hydroponics 3-part series. I will also be using calmag since I will be using RO water. Is there any other solution I will NEED to put in the water, or that is strongly recommended. Basically this is my first grow and I'd like to keep it simple, but if there is something I should be using that is simple and will make an impact, please feel free to share. Epsom salt? Flora nova bloom? Silica blast? H2o2?
Thanks!
Thanks!
