    Calm down dude, she is fine.
    Just watch the color of the trichromes.

    Some strains turn purple and/or blue in flowering.

    If she was pale green during flowering, she needed more N than she was getting.
    Lack of food and water during flowering can make them finish faster than norml
    So it seems to me, and is also strain dependent.

    re: Purple leaves

    thank you DAMAGO MAN.. i'm not that wooried, i'm calm lol..

    i dont think it's the strain, have any other ideals what could be wrong with her?

    first i thought it could be the ph,but when i feed her the ph is 6.4..

    it may just be a weak plant period.. i quess i'l just let her grow to see what happens..

    have a MERRY CHRISTMAS everyone

    Cannabis Plant and Pest Problem Solver - Pictorial
    "When your plants are deficient in phosphorus, this can overall reduce the size of your plants. Not enough causes slow growth and causes the plant to become weak, to little amount of Phosphorus causes slow growths in leaves that may or may not drop off. The edges all around the leaves or half of the leaves can be brownish and work its way inwards a bit causing the part of the leaves to curl up in the air a bit. Fan leaves will show dark greenish/purplish and yellowish tones along with a dullish blue colour to them. Sometimes the stems can be red, along with red petioles that can happen when having a Phosphorus deficiency. This isn’t a sure sure sign of you having one though, but can be a sign. Some strains just show the red petioles and stems from its genes.
    So pretty much the overall dark green colour with a purple, red, or blue tint to the fan leaves is a good sign of a Phosphorus deficiency. Having Cold weather (below 50F/10C) can make phosphorous absorption very troublesome for plants."

    re: Purple leaves

    I'm a new grower with some of the same issues you has with dark green-purplish leaves. I upped their dose of bloom a little and seemed to hold off any further decline.

    Good Luck!!
