Something's Wrong With My Plant... Please Help

Discussion in 'Growing Organic Marijuana' started by Ivanco, Jun 12, 2020.

  1. I have 10 plants in flower 4 different stains. Five of them are near the end of five weeks into flower and the other 5 are near the end at 10 weeks into flower.
    I have only one strain that's showing these symptoms.
    All the plants are in 7 gallon fabric pots, get watered every other day with just under a gallon/plant. I'm using well water before it reaches my water softener.
    My soil is
    Promix - 3.8 Cuft (gal. = 28.426)
    Worm Castings - 22.5 Gallons
    Perlite - 20 Gallons
    Dolomite lime powder and pellets - 9 cups (1 cup per cubic ft.)
    Azomite - 12 cups (1-1.5 cups per cubic ft)
    Amendments are...
    1.33 Gallons Amendment Mixture: (3 cups per cubic foot, 30 cups total of the following mixture.

    • Equal Parts: (except for Kelp Meal)
    • 8 cups Crab Meal

    • 8 cups Alfalfa Meal

    • 8 cups Neem Seed Meal

    • 8 cups “Happy Frog Jump Start Fertilzer” (in place of Tomato Tone)

    • 16 cups Kelp Meal (use 2x the amount of other amendments
    I used the recipe from the sticky Easy Organic Soil Mix For Beginners.
    None of the other strains are doing this and this strain started doing it about 5 weeks into flower.
    It seems to be the older dean leaves first and then by week 10 its affecting 70% of the leaves.

    I've attached a pics of a leaf and the plant that's in it's fifth week. 20200611_204826.jpg

  2. Take some pics of the whole plants with the containers they are in, in normal light (or in the dark with the flash on)
     
  3. Thank you Scoob. I will try and get that done this evening.
     
  4. I had an unexpected work trip so they had to veg more time than planned before they were flipped soo that's why theyre tall with long bare stems.

  5. Those burnt leaf tips are a sign of too much nutes. Looks like too much build up over time. I’d flush um well and see how they look in few days or a week or so.
     
  6. Many leaves will die off toward the end of the plants lifecycle starting from the bottom up but those tips are def burnt. Flush um
     
  7. You don't want to flush when using organic soil.

  8. Your plants look overall ok, I wouldn't be concerned about a few bottom leaves turning brown, I wouldn't do anything particular at this point just keep your regular routine. You definitely don;t want to flush.
    I would however consider getting bigger pots next time which will help them during flower when they need more available nutrients.

  9. Just under a gal of water every other day in 7 gal pots is not quite enough. I’m betting little to no runoff. He has a lot of amendments in that soil. The dynamic of that soil has changed and that strain is probably not liking it a whole bunch. When I say flush it I mean give it a good soaking so there is some run off. Scooby I know you don’t agree but that’s cool. Good luck with your grow

  10. That particular burn on the edges of the leaf says p/k deficiency to me. It might be pH related or not.
     
  11. Why not?

    If, for whatever reason, organic soil has become sodic or saline, why would you not leach the soil?

    OP is growing in relatively small pots, experienced longer veg' times, is using unfiltered well water, and used twice the amount of kelp meal normally suggested. Kelp meal comes with a considerable amount of sodium in it...

  12. Leeching yes, but that is different from the practice of flushing and should only be used in the case of an issue with the soil.
     
  13. I honestly don't see much difference between the two. It's just removing excess soluble nutrients from the soil solution surrounding the rhizosphere.

    Leach- agriculture
    "Flush"- potted plants

  14. The way I see it:
    Leach = removing access in the soil that would otherwise harm the plant if left alone. Typically when growing in organic soil one would never have to do this. Notice I said typically, there are of course exceptions like high salinity as you mentioned.

    Flushing = Removing nutrients from the media in order to starve the plant in order to improve the quality of the final product. Without even getting into whether there is merit to that idea or not, it doesn't really make sense with organic soil because as soon as you would flush the soluble nutrients, new OM will start to break down and replenish what was flushed. Not to mention the fact that the physical practice of watering the soil so much has potential to cause other issues if not done with care

    I don't think OP has an issue with access nutrients, if anything he is lacking in soil volume which is limiting the plant required uptake needs. That's what it looks like to me anyway.

  15. Thank you everyone for your comments and guidance in helping me correct this problem
    I will do as you suggested Scoob and ride this out at the moment. I have two other plants of this same stain in the first 5 I flipped to flower which are a week from finishing. Those two plants look like they'll be fine... the problem did spread a bit to the sugar leaves but has not continued to get worse in the last couple of weeks.

    All my plants started in 3 gal pots then were transplanted on March 28 into those 7 gals with additional fresh amended soil that had been cooking for a few months.
    I like to use 7 gals because I can move them around easier and for the space I have.
    I didn't expect to veg them that long and let them get that big.
    I don't plant on doing that this next time around with the ones I currently have in veg.
    So hopefully I won't have this problem again.
     
  16. I typically water until the bottom of the fabric pots are saturated with water and the pots feel considerably heavier than before I watered. I start with 3L and use more if I need to to achieve that. I have a couple plants that can take up to 4L. My other plants usually take just under 4L.
    I water in slow, let it absorb, and repeat until finished. Some pots have more run off than others because the water builds up and runs out the side of the pot. The pots that do this I can sometimes have up a 3/4 to 1 cup run off and they do take more water than the others that don't do this. The other pots I get maybe a 1/4 cup to heavy dripping.
     
  17. If you want bigger pots you can get casters and you can just roll them around with ease.
     
  18. Thank you for the suggestion. I'm in a 4×8 tent so I have to lift my plants out of the tent occasionally. These 7 pound pots get heavy enough when watered, I couldn't imagine lifting freshly watered 10 pound pots.
