    i doubt a plant @that age would worry about 600w - how much are you feeding these plants and how often?

    are you watering every day, or only when you feed? I get the impression from reading up on coco that you can feed constantly with proper mixture without issues as the medium does not hold nutrient or water. are you sure they aren't just starving or drying out? as Monster Energy mentioned, a 600w light would not be too much for those plants in their current stage of growth.

    You should be feeding at a low ec every day with 20% runoff.

    Need more info. What your background ec? Whats ec of final feed? How much of what per litre you feeding an how often?

    Like ladz said above coco needs be drenched every day once plants are well established an at least 20 30% runoff. I flood them every with shit load run off
