Phosphorus deficiency

  1. Just thought I'd post a pic of a problem I'm having.
    I think the P deficiency is being caused by low temps in the grow room during the dark period. The plant affected is in the corner of the tent closest to the open window(which is now closed).
    Hopefully things will pick up now that I've stopped the draft.
    Downside is the temps in the tent are likely to go up again.... :confused_2:
    If anybody thinks it's anything other than phosphorus please let me know :rolleyes:
