botanicare is a great 2 part product and is more organic than the rest
fox farm is got a great line of everything from liquid to soil.
general hydroponics has a great line of everything

their all great products its how you use them

generally the more organic you go the less salt build ups you will have and the flavor of the buds will be better and its also good to encourage micro biological life in the soil

i personally now like organic style of growing, it seems more simple and the plants love you more imo.
