    It could be that the plants are getting too much food and light.
    That makes them susceptible to all kinds of health problems that are impossible to diagnose.
    I often get these issues in hydro when I try more food and/or light.

    In nature, cannabis gets less light when autumn begins and triggers flowering.
    And the lower temp, and less growth requires less food.

    This plant is on the outside edge of the light. The one in the center and light side so no signs at all.

    I have two plants of different strains getting the same amount of food and light.
    One is suffering greatly from too much food and light, while the other is hardly suffering at all.
    (I was doing an experiment)
    Like people, even two plants of the same strain can have different needs.
