  1. I've been doing some research and it lead me to believe that my plant is having a nitrogen def. i also searched for way to correct this problem but everything i read was to use dry ice or c02 bottles etc. is there any other way i could add nitrogen to my soil? here is a pic of my plant, notice the 2 lower leaves, how yellow they are. also if anyone has to suggest that its some other problem please dont be shy :)
    also the plant is on day 13, the water ph before feeding is always about 6.4-6.5 and the run off is about 6.35-6.5...i also gave the plant its first feeding on day 8. i gave it 1/4 tsp>32oz of water using fox farms grow big....
  2. Anyone knows? Please?
  3. You make up for a nitrogen deficiency by adding nitrogen, not C02.

    Ammonia - Wikipedia, the free encyclopedia

    Chemical Nitrogen In Soil

    Most of the ammonia sulfate fertilizers are the big source of nitrogen and you can get a 20 lb bag pretty cheap.

    It doesn't look to me like you have a big if any problem though.

    First leaves sometimes do that.
  4. Nitrogen for plants can arrive in several forms... they are
    Urea (CH4N2O) (Methane + Nitrous Oxide)
    Ammonia (NH2 / NH4)
    Nitrite (NO2)
    Nitrate (NO3)

    Of these the only form that is assimilable by plants is Nitrate (NO3)
    This is true even with legumes.

    All plants require symbiotic bacteria that break down the higher forms of nitrogen down to Nitrate (NO3). To get from Urea to Nitrate requires three different bacteria all working in concert.

    So what does this mean?
    1) If you use something like Miracle Grow you will have nitrogen latency issues because the majority of the Nitrogen is provided in the form of Urea.
    2) If you plants need a fast N fix you should use a hydroponic type nute (like MaxiGrow) which provides nitrogen in Nitrate form.
