I'd go with organics...they're way more forgiving, and way better taste and quality! you can't go wrong with earth juice brand. they're 100% organic. fox farms bloom is o.k. but be careful with their grow juice- it has amonia which can burn yer shit DEAD! chemical fert's are liable to burn your weed if you're not careful....and remember faster usually does not equal better! also, study soil.the best weed comes from the best soil.
