    I'm fairly new to growing in soil. Since my first transplant with this grow, the fan leaves have started to canoe a little and are having some discoloration near the edges of the blades. As the fan leaves age they start to droop, the lowest fan leaves are completely limp. Also some horizontal curling at the tips. Any help would be appreciated. Thanks in advance.

  2. bump...any answers to this?? similar to issues i'm having now except I'm in DWC so over-watering is not the issue. I think personally it's light burn/bleaching, had my llight pretty close but moved it up tonight, just wanna make sure it's not something else.

    Sizzles, did you have your light low and then raise it up? Damage could just be showing up
     
  3. Thanks for the advice, much appreciated. Will cut back on the H20.

    No I've kept some distance between the light and the plants to try to keep temps down. It's most noticeable on the lower, older fan leaves. The top leaves aren't really showing any symptoms.
