Leaves rolling up

    So it's not really a problem so to speak, everythings under control and i'm not worried, just curious to identify why something happened.

    Had a clone in rockwool sitting in a heated prop, looking picture perfect, straight leaves, nice and strong and such, but needed to leave it a few days so filled up a DWC tub, ph'ed the water, and threw the rockwool into a pot to be moistened by the bubbles, everything as i normally do. Within 2 minutes of being in the DWC, the plant had kinda failed on itself, so i threw it back into the propogator. 2 hours later it looks like this.


    The right hand leaf shows it off best, they have curled up kinda like an orange peel. First time it's happened.

    Could be the PH twist?

    I havent seen anything like that on my grows but just a possibility.

    I wouldnt worry too much they are looking healthy other than that.

    Ph twist you say, that could be possible, i'll go read up on that. I'm not worried in the slightest, she's doing just great, rooted as well which is good, just curious by nature :)

    that plant looks great. i would snip off those leaves as soon as your roots start to take hold. the damage is most likely irreversible and the leaves are not going to be contributing to the plants overall health in that condition anyway. GL

    i know what you mean about curiosity. If i see something i have to look for it until i find it.

    As far as i can remember reading in URBAN GARDEN MAGAZINE there are 2 things that can cause this twist. One of them is PH and i think the other is too much N.

    But for gods sake dont quote me on that lol.

    Did you used a liquid type rooting hormone? If so you mixed it to strong. Or you pulled them out to soon from the humidity dome.

    This clone has been in the prop for about a week, it's already rooted (wee light coloured line on the far left edge of the rockwool is first root poking out). They did go from VERY humid environemt (i wake each morning to find the leaves of my mother plant dripping water strangely enough) to a much drier one.

    That type of twist is from one of two things that I posted or even both if you use the liquid rooting hormone to strong.

    It does not hurt the plant just looks strange.

    The cube is drying out too much between watering now that the roots are showing on the outside. Transplant to final growing medium soon. As posted above, if you used hormones and chemicals on the plug it may have been too strong. Upon transplant you should see improvement.

    The first few days after placing into the media in the bucket you should water through the pot a couple of times a day till the roots hit the water to keep the wool pellet moist. The water should be up to the bottom of the net pot until the roots emerge into the water then lower water to 1 in below net pot.

    I'm curious how this would be the case though. Prior to this occurring, the cube was constantly moist enough, and was regularly watered, so why would the DWC's bubbles cause this to happen and so instantly? Surely any exess gel would have rinsed off. Again though, same amount of gel etc used as previously.

    That is one of the reasons i did transplant it to it's DWC tub. However everything i did was exactly as i've always done with my tubs, same water levels etc, same ph, just for some reason this time no.

    the leaves transpired water faster than it could be replaced, and lost water pressure?

    In your case I would say it was a humidity change that caused the leaves to curl up, you went from a covered high humidity tray to open air in the DWC system,. witch took it from around 90% to about 30% I am guessing. You never hardened the clone slowly to less humidity over a weeks time. This is what caused the curl. If it was the rooting hormone it would of happen with in the first 24 hours of dipping them.
  13. It might be to hot try to find out what the tempertures get at throughout the day.
