    Default Leaf colour and burnt tips

    Quite a few leafs not looking the best so I thought I'd drop a post, as of last night I've adjusted the light to the right distance as the plants stared getting closer but I'm not sure the the light would be the problem here, I'll leave it to you guys who know what yous are on about

    Strain: stardawg fast buds auto

    Photo or Auto: auto

    plant age: 35 days from breaking soil

    pot size: 12L

    has it been repotted? and when?: never

    Medium: canna coco pro

    Air temps (max min): 20-25

    Res temps (max min):

    humidity: 40-60

    lighting type and wattage (hps, led, cfl): two invisible sun boards, each board running at 90w

    Light schedule: 22/2

    ph level: 5.8

    EC (hydro and coco only): 0.6

    Background EC: 0.3

    feed schedule and nutes: they get fed everyday with plenty of run off, over the last week and half id say the feed has been the same which is
    5 liters
    EC 0.6
    PH 5.8
    Canna Rhizotonic 2mpl
    Canna A+B 3ml of each

    I know im in soil and different nutes etc but with about 3-4 of my last runs with auto's, even when they have been fed nothing, i get burnt tips right before the buggers flower, does my head in but have never had any significant problem with it, just accepted its a 'given' with auto's. Hope you get answers.

    Top leafs look a bit twisted as well, could it be light burn?

    Sorry just reread the post, yeah my money is on a bit of light burn, I’ve had similar a few times now and it always seemed to be a result of me not raising the lights quick enough

    I have a plant doing the same thing. Left it alone and then the hairs on the top buds started to brown. I pulled my lights back a good distance now. I suspect it is the lights as well.

    Thanks lads I did raise the light I've been keeping close eye on them might raise it slightly more, that's one thing I need to check more regular is the light height, least the girls will be okay

    Has this issue been sorted since adjusting the light?

    I'd say so and the problem hasn't got worse, I think I need to tie these down again tonight, any ideas when to stop LST ? I think last time I stopped when they started to flower but just seeing what people think
