    No one posted anything, so I will try to offer some kinda advice. I am pretty new at growing, from my own research I think that, that is normal, but it looks like it may be drying to up much to fast what colore are your trichomes?

    Mag deficiency maybe? Add some cal/mag?

    My other guess is nute burn but you said it just started did you just up your nutes? It really is looking fried

    Why worry about a deficiency NOW???

    They look great. Really.

    Add nothing.

    Go ahead and flush with a week solution or plain tap water.

    They look like they are about 1 1/2 to 2 weeks away from finishing.

    If you're that concerned about the deficiency, it looks like a Calcium lockout from too much K, or high ppm tap water causing a K lockout. Both look similar. Too late in the game to fix, though.

    Good luck.

    And remember: you try to grow nice buds, not nice leaves! Look at the buds, man!
