Yellowing leaves... nitrogen deficiency?

    Coco/perlite. Using maxibloom as the only npk nutes, so it’s definitely lower on N. Using Si and CalMag too. Currently feeding at 1225 EC. Day 69 from seed.

    This is auto super lemon haze and it’s the only one that’s aggressively yellowing (and also the biggest one).

    Should I change ratio of npk for just this plant to more like 1-1-1? Maxibloom is 5/15/14.

  2. It does look like N def. However, at the stage of flower its normal for the plant to pull N from lower fans and use it higher up in the plant for bud growth.
