is it safe to use GH nutrients?

  1. Growing medicinal cannabis for the "hemp oil" is there any worry that heavy metals chemicals or toxins are released when consuming the oils?
  2. General Hydroponic nutrients are some of the best. Follow the Lucas Formula
  3. I think like w/ any fertilizer you'd want to perform a good flush before harvest to ensure any icky flavors go away. Most people just run clean water for a week or two before harvest. I use the GH line, w/ the lucas formula and it works great and I haven't had any adverse effects.
  4. I second that, been using gh nutes and the lucas formula for years in my drip totes and couldn't be happier. Flush for a week or two and there shouldn't be any heavy metal problems.
