  1. a freind of mine told me its 1200 ppm but I look at some of yall post
    and I see 1700 - 1800 . Iam trying to push them to the limit without
    nute burn
  2. it will differ with strain and alot of factors. its never a set ppm either. keep pushing it til nute burn thats the only way you'll know
