yeah but a nanner is nothing to really worry about. if you start seeing a shit ton of them, or if you are finding seeds in your weeds, then it's a problem with that particular strain. i have a couple strains that throw em and once in a great while i'll find a single bean.
as for the bottle saying organic, more importantly it should be an OMRI (or similar agency) listed product, but even still the list of things approved for OMRI, and the like, are not always the best choice. it's about knowing what's in your products and using your power to choose ones that meet the standards you want for your grow (yay capitalism! lol jk). I used to use the product Age Old Nutrients up until recently, and like you, I thought i was growing organic! boy, i was wrong! lots of the "organic" use salt base to cut their products; not all of them do this but the ones that are are making no claims to how organic their product really is. think about it, the word "organic" on your label just means you can charge more money for it. these hydro companies are trying to keep people hooked on the nutes so they can keep raking in the billions! the more organic you get, the more you will realize that you can be very sustainable in your grow room, keep costs ultra low after the initial investment of buying soil and all the fixings. then you actually get to recycle your soil and not throw any away! and more importantly have a cleaner product in the end, no matter if you're growing cannabis or veggies. I first learned about living soil from trying to be a better vegetable gardener cause store stuff sucks a fat one. i then had the brainstorm, hey i can apply this to my cannabis, and my patients will all get better medicine! now, here i am on ROI learning it up. there's a lot of knowledgeable folks on here and they will help you out. Good luck to you which ever method of grow you choose to apply!
