    It seems the mildew I found the other day wasn't enough. Upon checking on my rockwool cuttings, I noticed that they were literally covered in little tiny maggots!

    So, first question - what are they and how do I prevent this from happening again?!
     
    I threw all the cuttings away and cleaned the box with bleach, but I don't think that's enough..
     
     
    Now, as for my bubble cloner.. it has its own problem. I cleaned it yesterday with bleach and soap and today, it looks like I left it out in the snow. I dipped one end of it in water and the white stuff disappeared..
     
    What is this and how do I get rid of it or prevent it?

    And now for the worst part!
     
    Upon further inspection of all my plants, I noticed some sort of pattern on some of their leaves. It doesn't seem to be spreading but I need to know if this is mildew ASAP!
     
    Is it? If so, what do I do?

    Just as a reminder, these photos are of different plants. Please refer to which picture you're replying to. Thanks.

     
  2. Do the patterns wipe off? Looks like u have spider mites. The maggots? are fungus gnat baby's? Are the really small? The air stones look like they have salt build up on them just rinse them a few times.
     
  3. Fungus gnats are attracted to water/over watered medium.
     
  4. Agreed, and that medium looks drenched. Do you mist your plants and do you have hard water with lots of calcium? Could be that, as my tap water which I don't use anymore, would leave a white residue after foliar feed ( misting ) .
     
  5. Looks like thrips to me...

    The leaf insect pattern does resemble spider mites.
    Not sure what is crawling on your plants but definitely not normal sized maggots and waaaay to big to be fungus gnat larvae. They almost look like fruit fly larvae to me. I deal with all of these bugs with my fruit trees and small farm. (though they resemble thrips)

    Also, your plants look nute burned to hell. Those brown blotchy spots that appear in the middle of the leaf are indicative of fungus gnat larvae eating your roots.

    DONT ever use bleach to clean hydroponic stuff, it leaves behind the white residue you see on your sticks that others have mistaken for salt.

    If I was in your boat id seal off the room with 2-4 no pest strips for a few days. 4 days if the room is 8x8 and not a thing crawlin or flyin will be alive, guaranteed. Or you could spray a bunch of neem on them every few days and all that other expensive shit people use because it eventually works.

    Good luck buddy, got a lot to sort out.

    Oh, n id use pyrethrin (synthetic pyrethrum) to drench the roots of the plant before lights out as it tends to break down in light. Its a neurotoxin (inhibitor?). It will kill the fungus gnats within a week and any other living organisms in your soil so beforewarned.

    All of the chemicals listed above break down within minutes and are excreted in human feces, so no worries about cancer or other conspiracy bullshit.
     
  7. If indeed those are thrip larvae, I don't think neem will work.  I think you need some kind of Bt insecticide, like Spinosad.
     
    Neem is good stuff for almost all garden invaders, though.

    I'm not 100% sure they don't wipe off. I guess some could be water residue. But there's definitive silvering, which means I have thrips.
     
     
    The medium looks drenched because I just watered it.
     
    I don't usually get much residue and I'm pretty sure I don't have a lot of calcium in my water.
     
     
    Yes, it does.
     
     
    Yeah, I figured about the bleach.. though, it could also be my pH down material. I'll use H2O2 next time and clean it with vinegar now.
     
    I can't get no pest strips around here, so I'm down to using Neem Oil or Spinosad. More people like Spinosad.
     
     
    Actually, it appear the mildew I saw was actually something called 'silvering' which is actually caused by thrips, so I really only have the one problem.
     
     
    I heard that Neem Oil will take 2 weeks to work. So, I'm getting Spinosad insteadf.

    Yea well dont wait for all of them to jump up spray for everything at once. It would be silly to get a lesser treatment.
     
    All bugs can transfer mold, mites can ride in with other bugs and well bugs are going to be moving in constantly.
     
    Cover all your bases. $20 will do it all.
     
  10.  
    You want me to spray for mold and for thrips? I didn't realize you could spray for two things at once..
     
  11.  
    the stuff I linked to does it all. its good for everything.
     
    I try to make 100% sure all bases are covered before flowering.
     
    Iv spotted bugs in week 5 of flowering in the past and it will make you panic and be very upset!
     
    Its so much better to have everything done and done right. Then you have a happy harvest and dont feel like the whole harvest needs blasted into oil.
     
  12.  
    What you linked to was Neem Oil.. which people say isn't effective against mildew and not as good as Spinosad against thrips.
     
  13. Pyrithium bomb
