Just about every hydro shop bottle has a heavy metal in super small amounts. As do alot of organic fertilizers. Its negligible at best. And Terpinator says k sulfate. But you bet your ass thats not the only thing making the strains it worked on for me have more smell and trichomes. It only works with some strains ive ran. Its too expensive. And I quit using it after 3 runs years ago. But everyone keeps saying its just k sulfate. Its not. The labeling laws for fertilizers are wierd here in America. I suspect it has jasmonic acid in it but hey..what do i know. But k sulfate alone isnt whats doing what Terpinator does to plants. I also got this fake apricot taste on the back end of a toke on the strains it worked best on. Nah. Iam over Terpinator. Have been... its not that big of a deal.
