I am using Fox Farms Nurtients but I mixed it when I planeted them 3 1/2 weeks ago,I didn't over mix it.....huh Do you think possibly weed killer would do it?Reason I ask is my wife dosen't want me growing,and I have reason to believe she might had stooped to that level becuase of one of my bagseed plants that I planted last month I hid it and it hasn't had NO problems
