    What is the medium/runoff pH and PPM if in hydro? 7.5 ph

    What size pots? 1 plot unfortuanetly
    Any bugs? Look real close. had a single spider mite issue, some moths, and powdery mildew
    Any other pertinent info?
    The Purple Maroc is my smallest plant at about two and a half feet.
    to treat the spider mites and pm I used a garden safe 3 in 1 fungicide a friend had given me. I was unsure on the product but it was OMRI approved and to be extra safe I diluted half the recommended dose, only used once.
     
    So about a week ago, all of my plants had some brown spots, some had holes through them, and all had very little amount, except my Purple Maroc. She had a bit more than the others, now I have atleast twice the amount AND the tips of some of the leaves are yellow, some fan leaves turned entirely yellow.
    Pics below.
     
    Between that time I had used the Fungicide as previously listed, done my routine watering, and nuted them twice. I am about two weeks into flowering and really don't want to fuck my plants this close to the end.
     
     
     
    Any tips to help solve this dilemma and info to prevent it in the future are greatly appreciated!!

    You water every 24 hours on a timer? thats is dumb, you water when the pot is light, or once every 3-4 days depending on temps and weather.
    Interesting that you decide to kill mites and bugs with a fungicide, as I  they are used to kill fungi (mushrooms) like bud mold the PM.
     
    Understand as this is an outdoor grow, the plants done it's thing and wants to die, the only way to prevent that is to give her light to extend the day, to resume the veg or bud cycle, as the light is falling you don't need to give her so much food, as the photo motor has slowed, thus the consumption of nute has fallen, it builds up in the root zone, you may flush ...for a short term effect, but it's the long term you gotta solve
     
  3. those pictures made my stomach hurt, i got 3 plants in seedling/ almost vegging now, and your flowering is very disturbing to look at. 
     
  4. what kind of seed are these plz let me know so i wont purchase these in the future.

    I water damn near everyday because the soil dries and starts to crack, that's how I've been basing it.. Also, the fungicide had 70% neem oil which helped treat the spider mites, it was non systematic so I'm curious if it'll permanently solve my powdery mildew, which is the fungi, problem as well.  Granted, this is my first grow so I'm not going to be a 100% on what I attempt.. BUT what you're saying is the spots and tips are nute burn and I should dile back the amount used or how often or both? Also, how do I go about doing a flush - always hear the term, never fully understood what it meant other than just watering?
     
  6. @[member="flylikejordan"] Thanks for totally insulting my grow and then asking me the strain names -.- buuut the one picture is a Purple Maroc (2.5')
    I also have a bubblegummer (3.5'), Boss Hogg (5.5'), and Bomb Medi #2 (6.25').
     
  7. Huh..... !!!   I'm pleased you got Neem Oil, .. type of stuff there, and yes you will have some anti mold with Neem, better to look into getting some Neem Oil cold pressed for the next grow...?  as it's too dam useful!! ...lol
    Soil starts to crack ....wow, again should you grow in this spot next grow, better to add shit loads of organics to the soil, even some of the water wise silicon crystals you can get in garden stores ..?
     
    Meantime flush each plant with 3 x times the volume of the (pot?) or 6-8 gallons per plant (approx) allow to recover overnite or 1x day in dim light, no nutes for 1 week, after that nute them 50% less, increasing 15% at each feeding,
