Nitrogen Toxicity?

Discussion in 'Sick Plants and Problems' started by Fodolo, Feb 20, 2016.

  1. Ok so I'm getting the well known claw leaves and they are a lot more pronounced now. Also my older leaves are dark green. Is this a nitrogen deficiency? I haven't fed any nutes to the plant ever. So maybe it's just the soil?

     
  2. Need pics and setup, soil type, lights, RH temp etc
