    Default 5 weeks from seed, a bit of yellowing

    hi,

    im 5 weeks in to my first grow, its in coco, at the mo im using canna a and b, as well as liquid seaweed. PH is 6.5ish, and its at 600ppm.

    I think it looks ok, but im a little concerned about the slight yellowing, im not too sure what it can be, any ideas?

    You should be running your pH at 5.8-6.3 max and I would go ahead and drop the seaweed and just stick with a canna A&B.

    Looks like nutrient burn to me.

    Try diluting any nutrients further than you have been for your next few feeds.
