YOUR AVATAR SAYS A LOT ABOUT YOU! first off your a hater. i feel sorry for anyone on a cannabis site with hate in their blood. let me school ya a bit.... cannabis got it's freedom from rebels with balls, not spineless shit talkers..... now the facts are plants use B vitamins... what degree do you have? i have a 20 years of growing under my belt as well and a degree in horticulture oh i see you don't have true facts to go from, you must work at a nute company or your a pot head speaking from his anus! now i do not use the whole AN line and never would but i mix and match at my experience level you buy what your plants need. and a pro can see what his girls need and doesn't need instructions... facts are plants DON'T NEED BUT WANT EXTRA GOODIES. needing is when it has deficiencies. wanting is when a plant is healthy and fine but like a person going to the gym who exerts harder exercise than a normal person... his/her body wants extras.... it doesn't need them but it wants them... and when you give a organism what it needs 1st... so that it has basic overall health..... then you give it extras so it can concentrate on more vital process rather than having that organism expected to make all its own chemical process. it is a proven fact that adding supplements to any organism will result in less stress to that organism so that that organism can use its energy for other process. i will admit that like humans.. Plants can use vitamins... a plant takes what it wants and the rest does go to waste... but if you factor in the cost of nutes, water, electricity, trimmers... etc... you have plenty after spending top dollar on nutes.... expansion is part of any good experience... stay cheap and small your never grow as gall needed to go past the rest and be one of the best! AN products being compared to home depot b1 is so hilarious its unbelievable. when you get down the the ingredients home depots blue bottle has mostly and is used at a high rate per gallon in comparison. SO YES YOU DO GET WHAT YOU PAY FOR. I have used many brands of nutes. each company has a few gems that they make when you drop the hate youll realize that even AN with their kid like pics on the bottles has a few gems up their sleeve. so does H&G. so does GH and Nutrifield... etc... etc... etc.... if you skimp on nutes your skimp on true potential of a plant. i got trophies for my shit so don't talk shit until you can top that!
