RE: [APD] Removes "heavy metals"?

Hhhhmmmm... and just when I thought it wasn't an issue in terms of
removing/neutralizing micro and macro nutrients for plants!  :-)

Ok, once the Mg and Ca is chelated, is it still available for plants?  I
would assume it functions just like chelated Fe and that plants still have
access to it?
