    Did you feed them something different or did you add another light ?


    Do you have an idea of what caused this or maybe you have bugs that you cant see?

    Perhaps you can provide some further details of your grow and pics under white light would be helpful.

    It's only happening to 2 plants btw I'm using the gh trio calimagic liquid kool bloom just added and rapid root just stopped....water 750ml a bucket once or twice a day at 550ppm......just switched to 850ppm and 1.5ishL feeding last night..there were 2 power outages yesterday one for 3 hours in morning and one for 3 hours evening(came on hour b4 lights out) I think this stressed all the girls into flower...5hey all grew hairs over night.....can a mass defoliation of fan leafs cause this kind of stress?? They seem healthy.....growing in coco btw had 850ppms going in N 5-700 coming out......I did just switch to 400w hps from mh and put them in a grow tent at the same time....too much light?

    How far is the light from the canopy of the plants?

    Ahh I did lower it a bit .......pretty much dead on 18"....that main one it's happening to is the furthest from the fan so probably the hottest spot in the tent as you can see my little fan barely reaches it and fan into good blows all hot air right off the light that way......think its heat? I have 77 degrees there but I just opened a mess flap right there and doors wide open......I'll also add I can touch my glass.....

    I really dont think it could be heat stress. I added a littleiquid cool bloom and upped my ppms to 760ppm ro water ph 5.8ish mabye a little lower. I've fed them since everything else looks good this plant just wants to twist up at the top....I opened the mesh vent right behind it to cool it down I guess I'll just keep feeding and watching
    . I've just never seen such a twist. Usually s claw or something

    I had some Queen of Soul do the same thing, turned out to be from stress. I got a clone, vegged it out, cloned it, resexed it because it looked male (my cousin is just learning), then the next round of veg the leaves were literally growing in a spiral like Fibonacci sequence. My understanding is taking it from veg to flower to veg in such a quick time caused the stress, maybe putting yours under the "gas lantern" method stressed them out? How long have they been back to steady light cycle?

    It IS heat stress. And what method/medium are you using?

    Idk if GH contains enough CalMag in their base for him to not use CaliMagic with R/O water

    Just an update....this has not cleared up or gotten worse or seem to have any negative effects on growth....it is only happening on the top 4 nodes....so it basically topped itself and bottom branches are growing past it...I have flushed. Let dry out and re saturate. Fed just the gh trio now and nothing is changing just stopped top growth. My guess has to be light stress switching from mh ro hps as I went to 12/12 an hour a day from 20/4 so I didnt shock it that way
