will def read the link... but who told u nobody has ever flushed in the history of agro? I can tell u point blank that is false. Hydro tomato growers, right here in WA, flush their plants before harvest. Imo, one of the reasons its done with cannabis, is because we truly, HONESTLY, have no idea whats in most “cannabis specific” feed lines. They cop out & say its their “proprietary formula”. Tomato farmers wouldnt stand for that shit - wheat farm wouldnt, NO real agricultural farmer would tolerate that nonsense- theyd laugh in the sales rep’s face. They feed their crops EXACTLY what they need. And youre eating these agricultural products- you arent smoking them. It does make a difference. You mentioned tobacco farmers, which is an excellent comparison, and there ARE tobacco farmers that “flush”. They cut fertilizer & give only pure water - just like we do. A smoked product is different than a food product. Also, Due to the fact that multiple cannabis supplements/nutes have been banned AFTER being used unregulated for years, it stands to US, the weed grower, to ensure the quality/purity of what we produce. “Big cannabis” has repeatedly tossed cancerous BS into their products. The other problem, is that the average grower really has no idea what the exact nutritional requirements are for what theyre growing. Most over feed, then flush the excess. And due to how the nutes are mixed, giving enuf of one nutrient, can mean giving too much of another. It seems its in fashion to jump from strain to strain, mastering none of them. Lastly, Id wager that most of us have smoked weed with that horrible fertilizer taste, at least once in our lives. Even those who DO have their strain’s nutritional requirements dialed in, often flush, just to be extra careful to avoid this. Id put myself in the this category. Thanks for the link!
