    Mag def. I'd have to agree with the poster above.
    However do a google search for "cannabis nutrient deficiencys" and you'll find pics of all defs.
    A friend also wrote a book that is now all over barnes and noble and border's bookstores.
    It would be the best 13$ you'll probably ever spend.

    Epsom salt is good for magnesium.

    What SmknVTEC said.

    I'd say Potassium deficiency. do check out greenman's guide.

    I didnt add salt as in sodium I added epsom salt as in magnesium its the quickest way i can think of adding mag to a plant that needs it do some reading up on it its good stuff.
    I think you might be right about the Potassium def. I checked out greenmans page and that fits, thank you i will feed them some k and let you know.
