well, i mean, to be honest you would be able to go without nutes, until a problem arises. Its possible to use no nutes of course, weed has grown naturally for hundreds and thousands of years without people puttin budswell into the soil, lol.
But seriously, n i know your trying to go as organic as possible, but FF is organic nutes. If your using fox farm soil, go pick up some big bloom and tiger bloom. USe them together, and make your nuggets nice n chunky. Im sure theyll be lookin sweet anyways cuz of the strain, but the nutes really do help in resin production, thickness of the buds, and all around girth in general. If you do wanna go the pure route, thats totally cool, but youll rarely find people that do that anymore. Even purists that dont like chemical weed use nutrients, they just use umm...fuck i forget the name of them. Hold on, lemme look in my hydrofarm catalogue. Ill be right back man.
