Still can't figure out why sick plant dwc

  1. This plant has looked overwatered in DWC for a while now started off fine but last 2 weeks has looked droopy and the leaves are rolling and folding opposite ways...tips of leaves are dark and feel flimsy. I dont see any root rot and temps are good humidity is fine and giving regular nutes usually half strength ph is on too. Cant figure it out. I originally had the water hitting the net pot....just lowered it recently to 2" below. Airstone works good. Haven't given them calmag til this week because I literally forgot to include it. What would make the leaves turn inside out and outside in?

  2. doesnt look so bad ive had some cup like that no worries.
     
  3. Just wondering why the cupping and the tips feel dry but look dark and wilted
     
  4. i hear ya.. idk what causes it i just know i kept growing and had some dank buds.

    PH maybe? or overfert
     
  5. How's your light intensity? Even though the temps may be good she may be getting to much light. All the other boxes checked seem okay.
     
  6. What Light(s) are you using?

    What is the Temp, at the canopy?

    What is PH?

    How much FRESH AIR CIRCULATION/EXCHANGE, do you have? IMHO, for maximum health of the plant,,, and maximum use of light, plants need all the fresh air exchange possible. If not, one can quickly have to much light, for the amount of fresh air exchange available.

    Any fans blowing directly on the plant(s)?

    The Clawing of the leaves, can be caused by to much Nitrogen, and or overwatering. Or windburn.

    Cupping of the leaves, can be caused by too much light, which IMHO, often happens, because of not enough fresh air exchange. I run 1000w HID, at 20 or less inches, and never get light burn. But I have extremely good, fresh air exchange. Temps may get to 88f. And I make sure, every plant is slightly moving. I dont directly hit them with a fan, but make sure, they all have a bit of constant movement. This also makes for stronger stems. I also keep the same air exchange, when lights are off. Just the temps go down to 75f-78f.
     
  7. Definitely a lighting issue because those plants are already flowering.
