    Default leaves curling down/claws

    sensi skunk fem in black magic soil
    3gl pot, 900w vipa spectra LED's
    transplanted once 3 weeks ago

    1st week on 12/12, shes doing great and is getting huge, but the leaves are curling down, clawing, I have not given any nutrients and will be giving first feed in a few days, what would cause this? everything is pointing to nitrogen toxicity but how when I haven't fed her? its so confusing...

    Ill get some pics up soon im high and lazy right now but would love to hear some thoughts until i do

    I've had this a few times, imo could be 2 things....slight over watering and/or slight nitrogen overdose from the repot just have to wait it out, that's my opinion anyway 😉

    I would "guess" @ nitrogen being too high, would put them on water only.. plants dont need nutrients anyway...

    Ive had this with all of my plants,(and i dont feed until 4-ish weeks or the start of flower anyway.) Just think they make the soil nitrogen heavy these days.

    i water every 5 to 6 days, i make sure shes pretty dry before. the soil is pretty good at keeping moisture so it cant be over watering.
    I have not fed her any nutrients yet, i will be feeding her first time soon with CANNA terra bloom and Seaweed Xtra.
    the black magic soil is really high in nutes.
    Aged Bark
    Bat Guano
    Coco Coir
    Perlite
    Sphagnum Peat Moss
    Volcanic Ash
    Worm Castings

    but would that be enough to cause N toxicity from repotting?

    Different plants take to different nutes differently.

    I had to much N in the soil with this plant, it just went dark green.

    I had a sensi super skunk, could take loads of nutes and nothing happened until I got lock out from to much nutes.

    I'd just keep plain water that bad boy for now

    yea will not feed till I figure out whats going on

    i was just reading up that the leaves can also do this when there is a nutrient deficiency, I think i noticed some discolouration on new growth but didnt pay much attention this morning, will check when lights on.

    If its like a lighter green on the new growth thats normal. New growth is always lighter.

    Your fan leaves look a touch dark so id agree with above, dark green fan leaves and clawing, classic N toxidity

    yea thats exactly what it was. its annoying this is happening cause the plants happy and very responsive, super cropped 4 top colas and she was back up in a few hours. how long does N usually take to ease off the soil?

    It depends how much is in and if it's got any slow release nutes in.

    I don't know about your soil. You could always flush the soil, I did a mini flush with mine and it didn't seem to make much difference. When I watered I just made sure I got plenty of run off, about 2Ls of run off from 15L pot. I didn't get any clawing but plant leaves remained dark green.

    If I added any nutes it would burn.

    unfortunately i do have slow release nute balls in the soil,
    honestly tho I think she will be fine, looking at how big she is and getting, if it is too much N, it wont last long, im gonna try and not flush it unless i really need to coz last time i did that i had more problems as i let the plant starve after the flush

    Mines doing fine, although I don't have those feeding ball things in just soil is heavy N and sour diesel doesn't seem to be a fan of N.

    If your happy, keep doing what your doing!

    just gonna water till the N in the soil runs out, this is my second ever grow, first was a hindu kush that didn't go too well, autos don't like stress, not even a little.

    so far ive applied everything ive learned in these past months onto this plant, I lst'd her very young, topped her few weeks before light switch, supper cropped her and just pruned and lightly lollipoped the bottom and i still have LST going on in the middle to let more light go through.

    lets see if the tricks of the trade really give more buds
