Leaves Yellowing On 1 Month Old. Nitrogen Deficiency?

Discussion in 'First Time Marijuana Growers' started by Broodnath, May 19, 2013.

  1. 3 of my 1 month old plants are yellowing and drooping. It happened very fast, like within 2 days. It may be from overwatering, I water each plant about a half of a water bottle. They are in 1.5 gallon pots. They are growing currently in a mixture of organic potting soil/peat moss and 15% worm castings. I dont have pictures sorry, but my question: Is this nitrogen deficiency? If so, how do I treat it fast? I know you can buy spray but is it better to mix alfalfa in the soil?

  2. I'd check the PH of the water you're using and your run-off water.
    It's a possibility it could be nut. lock out
  3. post some pics if you can.

    one month old. might be a ph problem, nitrogen, or the start of a magnesium deficiency. might be in need of a transplant. Pictures would definitely help.
