Why R They Yellowing

  1. Hello,

    Lately, I have noticed my leaf tips are curling downward on all of my plants. I am feeding every other day using cocotek A&B, 10ml per gallon. I am growing in FF ocean soil.
    All are bagseed so I have no idea about genetics.
    Currently in red cups.
    This is now week 7 of veg.

    I will be putting them into flower next week if I can resolve this problem.

    I thought this was a nitrogen deficiency problem so I doubled up on nutes for the past three feedings but the leafs are still curling downward and turning yellow, and crisp. Starting with older growth.
