    Default Dark on buds and leaves. Freaking!

    Evening all,

    Been a while since I've had a freadout.

    Growing a few white widow autos in 8l root nurse using plagron grow mix soil and ot nutes. 200 w cfl

    She's on day 87 and temps are typically between 22 and 26 with rh usually about 50%.

    There are a few leaves on the cola that have dark edges possibly black or purple and some of the bud is showing a purple black hue to it.

    I thought it was initially purple as it's been cold at night recently.

    You're my only hope obi wan

    looks more like nutrient burn 2me mate,
    the burnt leaf tips and edges are a clear indicator of high levels of nutrients, hence the tips look burnt/dead

    just dial the OT nutes back and she'll bounce back in no time mate


    the purple color that gets brought out via the cold temp and not the phenotype
    its just a stressed plant since cold temps drastically affect your plants root system and the uptake of nutrients esp magnesium mate

    if it's only the last few days lower temps won't hurt anything but id try and avoid it in early/mid flower

    your doin great using a 200w cfl bud,

    Would love to see pics of the whole plant. I'm also trying to grow autos under cfl in a low space. What height is yours now. Did you top or lst much?

    You look close to harvesting... how long till the flush begins?

    Alright buddy, I'm having problems with the uploader or my phone so can't post others at the moment. I've got 2 WW going. One is 60cm and the one above is 30cm. The larger one has had lst.

    WW is quite forgiving so far and my last grow with it was far from ideal but still took 44g dry. Flush is on now!

    Cheers for the info mate. Im having the same issue uploading. Just got a new phone so haven't tried figuring it out yet.

    So the one you did LST on grew taller than the 30cm plant that u left to grow normally?

    The smaller one has indica leaves and I think the lowryder or whatever makes it auto is dominating, it's just been shorter and squatter.

    The bigger one has sativa leaves and was racing away from the moment it sprouted so I was tying it down to contain it. My tent at the moment is only 50x50x100, it would've been touching the top otherwise.

    What you planning on growing?

    I've got 2 NL autos about 8 weeks old. You've got 10cm on me as my tents the secret jardin DP90. It's meant to be a propagation tent but I need to make it work for me so tried for a short strain with LST and cfl. Still struggle with height tho... Wish I had at least another foot. Heats tough too but it's in the house atm. Soon it'll be in the cabin so hopefully with a fresh air intake it'll get easier

    With 2 fans and a decent intake and outtake I found the heaterm very manageable. I've just gone into a 60x60x140 and giving led a bash. No concerns about heat now!
