The shotgunners love that pure lead stuff though.

You can get the tea tested for lead, no need to even mention cannabis. That would tell you the concentration of Pb in the tea by volume...then you could gauge whether you should toss it. This is more chemistry than im interested in pursuing...chelating ions, humic acid, nitric acid, even ph affects what happens to the lead. you can do a CalMag soil drench and that may oxidize any lead hanging out in the coco and drain it out. Dont reuse that coco.

FWIW, I tested two water samples for Pb contamination. Sample #1 contained the two 1 ounce Pb sinkers, placed in a quart of RO water for three days. Sample #2 was compost tea brewed with the sinkers for 3 days. Sample #1 tested a Pb level higher than the EPA standard for drinking water. Sample #2 tested safe for drinking. So it does appear Pb leaches from sinkers; more than likely the "hungry" RO water accelerates that process. For the compost tea, the result may be due to the binding of Pb to the phosphates in the tea or to the organic matter, per the research.
