I'm thinking of "Fox Farm Trio Soil Formula" or the "General Hydroponics Flora Grow, Bloom, Micro" which should I use? for my measurements should I follow their MEASURE CHARTS SYSTEM for the weekly grow? Not only that but do I need Cal Mag? This is really too much to need to understand about growing but once I learn I know I will make a good fortune from being a grower. If anyone can help just explain the simple nutrients I will need for my first grow ever. Nothing too complicated which I can handle but I see it's a process a bit for the use of nutes... Thanks
