    Edit : Tabled for readability
    Strains : Tangerine Dream, Blue Dream
    Medium : Hydro, 5 gallon DWC hooked to recirc, 3 bucket system ~ 11 gallons
    PPM : 1100
    pH : 5.8-5.9
    Feeding : refill res with 800-1200 ppm water phed to 5.8 every feeding
    Bennies : Tea of EWC, and bacillus subtilis and mycos with rockdust to bind on and molasses to eat, 2-3 cups poured into main res of system every 3-4 days after a 2 day brew.

    Flushed : Day after this post, once during flowering transition 3 weeks ago, never otherwise
    Nutes : Flora Nova Bloom 4-8-7
    Problem : copper-rust colored spots on tops of leaves, shriveled/withered leaves curling in on themselves

    Bugs : No bads

    No idea whats going on. PPMs are like 1200 and pH 5.8-6.0. Dunno temp ranges but they seem fine (no yellow or purple of new growth)
    Everything was going swimmingly in my outdoor DWC and then these little dots started showing. When they didn't spread I assumed nothing of it, and that it was a result of my never changing the res. Recently I added some H2O2 to kill a potential rot; but the concentration was so incredibly low, just a few capfuls of 3% within 6-9 gallons water. After that the curling/twisting happened and those dots spread.
    What's confusing is that this girl is part of a 2 plant 3 bucket recirc. She, tangerine dream, has these issues while the blue dream in the other bucket looks almost totally fine (except for an instance where ONE branch is wilting)

    Has anyone seen these symptoms? The plant looks fine as a whole, but if you look closely a leaf or two here and there have gone wack.

  2. Looks like PH issues to me check this plant abuse chart out and towards the middle of the page is a pic of a leaf that kinda looks like yours.:smoke:
     
  3. Spider mites. Check the underneath.
     
  4. Is that what that looks like? I knew it didn't look just like ph issues but that was my best guess. Never dealt with spider mites luckliy none have made it in my house(knock on wood) so I'm not familiar with what the damage would look like from them.
     
  5. ...you don't have spider mites...you'd see millions of white/yellow spots and you'd find little black mites on the back-side of your foilage....the copper spots could be pH or nutrient related.

    Its not a pH issue; the pH stays at 5.8 and RARELY raises to 5.9 let alone 6.0 - I add a tea in every other day that keeps the pH constant.

    Its not spider mites. That would show as white dots up top, not reddish orange.With the extent of damage, I'd easily see them by now as well.

    @trichomefiend how would it be nutrient related? In other words, what nute defic/burn can cause this?

    Some additional info : Last night I flushed the system with 10-12 gallons of water mixed with generous amounts of sledgehammer. After that I ran 30-50 gallons of water through until foam stopped showing up in the main res, at which point I put in new water pHed 5.9 ppm 1100. The flush sure as hell worked, as the leaves began losing chlorophyll towards the end. Pretty sure that takes care of salt builds

    Edit : Whats worrying me is the curling leaves on the tangerine dream. After the flush those rust spots began showing on the blue dream as well (Though I upped circulation by an incredible amount to do the flush, maybe that brought the problem to her) so I'm leaning towards some sort of defic or root attack. Adding beneficials to take care of root issues, so now I just need to eliminate nutes.

    What nute defic would cause those rust spots; anyone?

    That is why I said check the underneath. Oh superior all knowing one.
     
  8. ^zoom, its 100% not mites. I don't need to check underneath; mite damage is white.

    Good Lord. I was making a suggestion first off. Second , if you knew it wasn't a bug from jump then you should of said that. I think its amusing that ppl come on here asking for help then get their panties in a bunch over a suggestion. If you want help then YOU have to give complete information Or don't Get butt hurt when something is suggested. Yes, i'm in a bitchy mood. But that doesn't make the content of my post less true.
     
  10. ...
    Ok.
    FIRST OFF (heh) I was posting that so anyone who pops their head in, such as jinn420, WON'T get the wrong information. Not because "my panties are in a bunch".
    I guess my bad on not specifying I don't have a bug problem and my bad on trying to help the GC community as a whole; don't need to get butthurt when people point out what is faulty with your diagnosis - I'm not going to compromise other peoples grows to make you feel good about your contribution.
    Thank you for your attempt help, I really do appreciate responses, but there's no reason to get so bitchy over someone proposing an opposing opinion. If you want to continue this discussion, please PM me instead of cluttering up the thread with personal issues, thanks.

    Back on topic:

    Can a nute defic cause the rust spots? It doesn't look like Ca pictures I've seen, plus I'm using tap-water. - any other deficiency makes no sense to me. I added some epsom salts in just in case, and some micronute formula in addition to the 1100 ppms resulting from flora nova bloom addition.

    Could it be a burn?

    Could the curling be caused by H2O2 damage?

    :cool:...well, at the 1st view of his pictures, hopefully you seen brown/copper spots on his leaves just as I did :confused_2:...if you have had any experience with spidermites you would know that brown/copper spots are NOT a sign of them being present :rolleyes:....so let's just get real here, you do not know and your passing useless/misleading information....that's real.

    ...not here to debate, I'm here to speak facts.
    ...but on another note, you can shit and fall back into it...keep your attitude peasant.
     
  12. Did you ever figure it out??
     
  13. Problems in the root mass leading to nutrient deficiency thought to be Ca/Mg or some other water soluble salt.
     
    Never could fix as the flush agent (FLUSHING AGENT : Sledgehammer, DO NOT BUY) caused a ton of issues. Immediately after the flush both plants became weak and deficient. Root rot started to set in heavily in both plants; in the tangerine dream there was likely rot already present in the center of the root mass and the sledge exacerbated it. Decided to scrap em.
     
    Learned from this grow that a month is WAY too long to vege a plant in a 5 gallon DWC... heh.
