i dont know i think slik wil may have a point. im only two weeks from harvesting itll be 10 weeks with my pineapple kush, and its my first. im guesssing that the chemicals are molecularized before they produce the bud.I dont think its like nutrients running through the bud, that may be only the stems and the "veins" of the plant. They simply use the elements we so care for, nitrogen potassium etc... But the difference between vegetable farmers and us is that we BURN our product to inhale the fumes. This bud should only contain the end result pushed by the dna of the plant, and not chemicals inside of it, but it is true that synthetic chemicals wil remain in the plant tissue wherever it may be. Same in human beings, pesticides sprayed on our tomatoes are eaten by us, and it remains in our fat tissue forever, possibly causing one of many cancers we are still discovering today.
