    First time growing and I’ve used 4 different autos in coco peat and 300w led all set up properly but the plant looks like it’s dying or something can someone give me an idea what’s going on

  2. How close did u have the light? What's your nutes, rh, watering schedule, pH? Need information.

  3. Yep
     
  4. Ok so I don't see an LED doing that...like if it was going to be heat burn I'd imagine something that gets hotter doing that. I haven't personally used LEDs though so...maybe someone that has could weigh in.

    I think you may have over-fed them?
    Seems to original at the edges of the leaves which I've seen in nute-burn before.

    Dumb question - You *are* using nutes for coco right?
    Did you give them at the strength recommended on the bottle? (because at that size, I wouldn't go full)
    Checked PH *after* adding nutes etc to water?

    Your coco also looks a bit tight? Maybe consider mixing through some perlite or vermiculite, and make sure you have something down the bottom that will help things drain.

  5. I mean at this stage you do have *some* healthy growth in the middle so they're alive for now...but you'll probably want to figure it out fairly quickly.

  6. Got the light about a meter away from the top of the plant I have no clue what ph it is I’m gonna lend a tester off a friend tomorrow didn’t give it nutrients for the first 10 days but then I used some advanced nutrients because it was curling up and had white spots on the leaves

    Only put a micro dose of each one into a litre bottle (it says to use grow micro and bloom together as a 3 part) was doing it once every 3 days but then it looked really dry when I decided to put nutrients in, since then it’s got worse, the coco is quite damp still idk If I overwatered it or anything, like I said this is my first time I don’t have a clue haha
     
  7. Sounding more and more like your pH is outta whack!

  8. I’ll get it checked and get back to you
     
  9. Looks very close to over watered symptoms could always try fresh new soil n not so much water just a thort what ya got to loose at this stage..

  10. Yeah bro....hopefully someone with more insight will show up with some advice for ya in time to save em. I honestly don't know what that could be....i mean, it could be it has some kinda fungus from being over watered for a bit too long.....it could just be water-logged.....if you haven't been checking PH, there is a good chance its off.

  11. Im a noob but I think you need some perlite to increase aeration in the soil

    image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg Sooooo i got a ph tester and the tap water was 8.5 no idea why, however I have switched to bottled water with a ph of about bang on 7 every time, completely removed them from the coco cleaned the roots off in neutral water gently and put them into plastic cups with holes in with soil and perlite.

    shot them back the light and waited till it was completely bone dry before I watered, removed the coco out the room I think the wet coco was making the room real humid, since then I've had a massive difference in progress.

    I haven't used nutes again yet since not sure whether to yet.

    Here's some photos of what I've got now, you can see where the old leaves have died off and new ones replaced them, only thing I notice now is kind of a browning on the tips of the leaves, and some of them change texture towards the tips idk why, one is being a lot more resilient than the others, and the best looking smallest one is one I had to plant again to replace one that died.

    I'm using a light cycle of 18/6 since I want to give them some time out the light just in case
    Using a 300w mars hydro at approx 60cm above the top of the plants
    Also I'm now only watering when i can feel the soil is crispy dry
    Should I put a on of them pound shop plastic dehumidifier in lol?

    I'll also post a pic of the nutes I have and my set up :)
    Hope you guys can help me further now I've gave all this info
     
  13. So you’re mixing peat and coco?

    Or is it just 100%coco?

  14. 100% canna soil mixed with perlite
     
  15. image.jpeg It's looking well but the leaves have a bit of a weird colour

    Magnesium_Deficiency_in_Marijuana_Plants.PNG Magnesium_Deficiency_in_Marijuana_Plants.PNG It looks to me that your plant has a

    Magnesium (Mg) - Micronutrient and Mobile Element


    Magnesium helps supports healthy veins while keeping a healthy
    leaf production and its
    structure. Magnesium is significant for chlorophyll-production
    and enzyme break downs.
    Magnesium which must be present in relatively large quantities
    for the plant to survive,
    but yet not to much to where it will cause the plant to show a toxicity.


    Magnesium is one of the easiest deficiencies to tell… the green veins
    along with the
    yellowness of the entire surrounding leave is a dead giveaway, but
    sometimes that’s not
    always the case here. In case you have one of those where it doesn’t
    show the green veins,
    sometimes leaf tips and edges may discolor and curl upward. The growing
    tips can turn lime
    green when the deficiency progresses to the top of the plant. The edges
    will feel like dry
    and crispy and usually affects the lower leaves in younger plants, then
    will affect the
    middle to upper half when it gets older, but It can also happen on older
    leaves as well.
    The deficiency will start at the tip then will take over the entire outer
    left and right
    sides of the leaves. The inner part will be yellow and or brownish in color,
    followed by
    leaves falling without withering. The tips can also twist and turn as well
    as curving
    upwards as if you curl your tongues.


    Excessive levels of magnesium in your plants will exhibit a buildup of toxic
    salts that
    will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can
    get locked
    out by having too much Calcium, Chlorine or ammonium in your soil/water.
    One of the worst problems a person can have is a magnesium def caused by
    a ph lockout.
    By giving it more magnesium to cure the problem when you are thinking you
    are doing good,
    but actually you are doing more harm then good. When the plants can’t
    take in a nutrient
    because of the ph being off for that element, the plant will not absorb
    it but it will be
    in the soil… therefore causing a buildup. A buildup will be noticed by
    the outer parts of
    the plant becoming whitish and or a yellowish color. The tips and part
    way in on the inner
    leaves will die and feel like glass. Parts affected by Magnesium deficiency
    are: space
    between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.




    Problems with Magnesium being locked out by PH troubles

    Light Acid Soils, soils with excessive potassium, calcium and or phosphorus


    Soil

    Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
    Magnesium is absorbed best in soil at a ph level of 6.5-9.1 . (Wouldn’t
    recommend having a
    ph of over 7.0 in soil) anything out of the ranges listed will contribute
    to a Magnesium
    deficiency.



    Hydro and Soil less Mediums

    Magnesium gets locked out of Hydro and Soil less Mediums at ph levels
    of 2.0-5.7
    Magnesium is absorbed best in Hydro and Soil less Mediums at ph levels
    of 5.8-9.1
    (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.)
    Best range for
    hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges
    listed will contribute
    to a Magnesium deficiency.



    Solution to fixing a Magnesium deficiency
    Any Chemical/Organic nutrients that have Magnesium in them will fix a
    Magnesium deficiency.
    (Only mixing at ½ strength when using chemical nutrients or it will c
    ause nutrient burn!)
    Other nutrients that have magnesium in them are: Epsom salts, which is
    fast absorption.
    Dolomite lime and or garden lime (same thing just called different)
    which is slow absorption.
    Sulfate of Potash, Magnesia which is medium absorption. Worm Castings,
    which is slow absorption.
    Crabshell which is slow absorption. Earth Juice Mircoblast, which is
    fast acting. (a must buy!!
    Has lots of 2ndary nutrients).
    Now if you added to much chemical nutrients and or organics,( which is
    hard to burn your plants
    when using organics) You need to Flush the soil with plain water.
    You need to use 2 times as
    much water as the size of the pot, for example: If you have a 5 gallon
    pot and need to flush
    it, you need to use 10 gallons of water to rinse out the soil good enough
    to get rid of excessive
    nutrients.
     
  17. It's 100% canna soil and perlite now I got rid of the coco
     
  18. Plant has a...
     
  19. Anyway just add Epson salt to your next few waterings and your plant leaves qill start to turn green again. This very same thing happened in my last grow and I did this and my plants were back to normal very quickly.
     
  20. Cheers mate, can you get the Epsom salt from shops or do I need to order it online? I added some nutes to a different plant a bit older and it seems to be thriving, it's very green compared to that one, I think I'm doing something right I'll update in a week or so
