I've only got 4 seedlings growing atm they all look decent save for 1 it's growing funky but still green..I've got a 6inch fan to stir the air...exhaust port but now exhaust fan yet..temp is between 75-82 with the lamp on and 75-69 with them off..RH between 40-50% I live in el paso it's pretty dry here..

    So I got an Euphoria, and the plant just keeps growing, but 11 weeks in, I still can't see a single flower.
    Harvest should be early october and flowering time should be 8 weeks, so I'm getting a little worried.
    The setup is outdoor, so any suggestions?
    12/12 hour sunlight might be a little hard to do, but I could try to get as close to that, but dunno? [​IMG]
     
  3. I *think* it is too late in the year to be growing non-auto strains outside. I could be wrong on that one but that's what I suspect. In my vast knowledge about cannabis cultivation(I am such a newb but waiting to begin my own grow) I would say you need auto flowering plants to grow outside passed July. Best of luck and somebody please correct me if I'm wrong!
     
  4. Sorry I may be in the wrong room, I'm growing outdoor and recently have had an outbreak of yellow leaves, I'm about 3-4 weeks into flower and some of the yellow leaves are dried out like crispy even though my soil is still moist, any clues?
     
  5. Sounds like a fertilizer problem. You may be fertilizing them to strong or to weak. The ratio of nutrients needed at the 4 th week of bloom is much different then the grow cycle. Nutrients also get built up in the soil which can cause problems, it also changes the pH of the soil when locked up.
     
  6. Sounds like it's short P & K for Blooming...
    .
    I'm three weeks into blooming...
    .Growing outdoors... WAY up north
    All I've used is Fish Fertilizers ...
    Both are the Brand "Alaska"
    The Fertilizer is 5-1-1
    and the Morbloom is 0-10-10

    It's not a picture that gets bigger...
    Looking far away I'd say second week...
    Hope your in an area that lets it go 6 more weeks...
    .
    Cause right now... It's not in the money yet...
    Got a scope ???
    $12. bucks at Walmart.... 20-60 power...


    I only look at the Trichomes....
    It's the ONLY way to go...




    I had to chop mine at 6 weeks ( ( 6 plus ? )
    Because of harsh weather in upper Mid-West

  14. Looking for some advice. I'm a new grower and haven't got much experience with my climate / light cycles. If you veg a plant outside for 24hrs using LED spot lamps at night will you be able to get them to flower with 15/16 hours days in sping/summer? Heard the indica's cut off at about 14 /14.5 max light.
     
  15. Looking for some advice from someone experienced with a 30° south latitude. If veging plants 24hrs outside using LEDs spot lamps at night will they flower properly when switching to just day light? Summer hours peaking 21 Dec at about 14hrs day light and 1hr civil twilight. People in my area are saying very different things so thought I'd seek some expert advise before I have 20ft plants in my 30L pots and will only be smoking in April!
     
  16. Hey everyone,
    I am in trouble. I put two plants in on 6/21. I lost the second pictured and replanted it on 8/20. I turned the bloom light on the 1st pictured on 9/14 and split the room about 9/20. I run the bloom light on a 12 hour cycle but Ntcs%NQsQgmsO0n+JMp3KA.jpg dBEo7pfUSLC6kjN7v1M0kQ.jpg the 2nd pictured plant is still on a 16 hour cycle. Is the bleed over light keeping the 1st plant from budding? If so I will pull my divider and turn both bloom lights on. I just recently backed off the nitrogen and am trying to force bloom with high P&K. Help!
     
  17. informative one. thanks.
     
  18. Try your best to simulate the fall season. Slightly lower the temperature in the greenhouse and increase the ventilation to reduce the humidity. If the plants are reluctant to respond to changes, you can also reduce the daylight hours to about 10-11 hours. In other words mimic a natural habitat.
