Very light new growth. Deficiency or is it nothing?

Discussion in 'Growing Marijuana Indoors' started by quidado, Oct 16, 2014.

  1. Looking for help figuring out what deficiency my plants are dealing with. Some pictures are better than others because of the lighting. The top growth is coming in a very light green, which has been normal for me in past grows, but this is much lighter than usual.
     
    I've consulted sick plant charts but I'm just looking for peoples opinions
     
    In these picture you can see how light the new growth is:

    In this picture you can see some color issues in some lower growth:

    And here's just some random shots, that look ok

    I switched to 12/12 on October 5th. But the light schedule fucked up and ended up on for 24 hours. I corrected that on the october 12th.
     
    During Veg I was feeding it a 4 - 1 - 4 tea(sorry forget brand right now) but had a nitrogen deficiency so I gave one 1/3 feeding of Miricle grow all purpose 24-8-16 which gave me some burnt leave tips.
     
    in attempt to correct the mentioned deficiency, yesterday I gave my plants 1/3 dos of Miracle Grow Ultra bloom 15-30-15. I'm hoping that helps, but I'm wondering if there's anything else I should be doing.
     
    Water Run off Ph is around 6.6
     
    Using organic soil.
     
    5 gal pots
     
    If I've left anything out, please let me know. I know everyone hates Miracle Grow, but I've had success with it in the past. Though, this is my first time using organic soil, so I guess I'm more dependent on the fertz, as in the past I did not have to provide much.
     
    Any input would be appreciated.
     
    Thanks.,

  2. I should also mention Temps are between 75 - 80 with lights on. 70 - 75 lights off (I've seen it go as low as 65 at times)
     
    Also Humidity hangs out around 50% most of the time.
     
  3. i don't no what's up with them but i must add you have some very nice plants and expect for the yellowing they look very happy,how long did u veg for?
     
  4. Thanks! I vegged for 50 days. Topped each plant twice.
     
  5. Very light growth, from my newbie experience, is an N def. Going into flower though, I would flush it and give it some flower nutes with a decent N rating.
     
    I'd steer away from miracle grow too, you're plants would be growing better without their chemical food.
     
  6. Honestly, the Miracle grow nutes haven't done me wrong in the past, as long as I use low doses, and flush regularly. My first feeding during flower was a really low dose.. maybe I'll up it and see if that helps. and I'll also continue to give it, its 4-1-4 tea.
     
  7. Well things seem to be greening up a bit and I've yet to do anything. I guess it's common when switching to 12/12 and seems to be fixing it'self on it's own.
     
  8. Lights just came back on.. They're looking so much better
