I do some are good some can be loaded with nasty stuff or be high in heavy metals thats why i like biobizz personally i prefer organics ive grew with canna in the past too tho but i prefer organics definitely mind you im a bit green thumbed with all plants not just weed and thats how ive done it with everything else so yeah dont get me wrong i aint saying you cant grow good weed with synthetics you can of course grow good weed with say canna for example you can just imo avoid that nasty minty flush shit they sell that stuff can ruin crops lol but if you gonna try a new brand of nutes then i would always dig deep on it first if was me obviously skill and handling and environment dictate most of the quality but i do think nutes play a role even if it is small everything adds up as they say
