    You stated that the taller the plant got it started to curl. How far are your fans,and do they oscillate or still? It could possibly be a wind burn as well,just a thought. Good growing…✌

    heat stress maybe? what's the temps at the at the plant tops acting retarded?

    Seems like the leaves are trying to bend according to the light, agreed. In my last grow in my 4×4, i had some leaf curl only on the very edges of the scrog, but ones in the center had no clawing at all. So it is more likely a light related curl.

    Im getting "clawing" and I am pretty damn sure its from my light being to close.

  • Dontsurf 805 1 year ago

    how far are you lights spaced apart and how far are you plants started from the light?  Where is the video for day 60?

    Agreed, clawing on vertically grown plants is generally phototropism in my opinion.

    i think if you covered the top even with white or mylar you would have got more of that light back onto the plants and not lost on the roof

    isn't it just the leaf blades angling themselves towards the light?

    Imo it has to be some.kind.of environmental factor. Light,Co2 or something. Your feeds in coco are pretty dialed in. Probably a good decision though to be safe and flush if you have been daisy chaining more than normal.

    I dont think its nitrogen toxicity,Ive seen this before. I believe it has more to do with the vert setup and the way the plants transpire water. With traditional overhead lighting the leaves sweat off the water evenly, but with vert the tops of the branches dont get enough direct light so there is an imbalance with how much water they can transpire and it causes the leaves to claw like that. The animal cookies top vs mid sections displays it pretty well as you mentioned

    The big Canadian vertical bulb cea grows I've seen don't seem to have the clawing issues.

    And just like to note that "yellowing off" doesn't happen.. Outdoors in a natural environment only a few leaves turn yellow out of thousands. In indoor contained root environment yellowing is due to salt build up causing ph issues and hot spots. Its a health issue not a natural occurrence.

    I think the downward canoeing has something to do with heat from open bulbs coupled with lots of air (fans) blowing around the plants. Imo seems like the prob gets worse near fan direction.

    This generally happens to me with too much cal mag supplement from botanicare. I wish they would make a phosphorous based cal mag supplement instead of a nitrogen based supplement
