Spent about 10 seconds on google, doesn't sound like a good idea bro...
Among the many things spoken of on its wiki page and in the summaries of a single google inquiry, it kills bees and is a big suspect in CCD
.Well I think there will always be some amount leftover and to me that is not worth the risk. But in reality I don't know enough to say if the amount (depending on how much you use) will remain in flowered bud, hell it probably wouldn't be all that bad with how beneficial the cannabinoids are and how much growing a clone can do (but again, I wouldn't take that risk for users or the environment). I advise to find another less toxic product, and/or grow indoors (LED just as capable as HID with 75% or less heat watt for watt)
Wiki says its readily uptaken in the plant, I'm not one who believes flushing removes anything from the plant (it only removes stuff from the growing medium). Flushing can actually lock stuff into the plants even worse when they can't get certain resources they need to operate properly (kinda like how some vitamins/minerals are useless if not consumed with certain others,)
Thats the idea some people got, but really it was mostly for chemical nute growers to help rid their growing medium of salt build up. If you wash out certain nutes too quickly the plant certain operations go into lockdown mode because suddenly there is no food (or like with the vitamins, certain resources become useless). If one feeds properly, or uses organic nutes you don't really need to flush. Just water like you normally would but don't add nutes, or add less and less each feeding the last few weeks. Flushing is for big fuck ups, like if you feed way too much of something on accident. Also a lot of the stuff people blame on not flushing is because of improper drying and curing of flowered bud (or the fact certain chemical nutes were used which flushing wouldn't help)
