    sativa is turning yellow

    i wouldnt worry to much about it, flowering plants' bottom leaves start turning yellow and falling up and it will work its way up, when did it start? i think around 4 weeks into flowering is pretty normal but if it was alot earlier than that, than it might be something else

    sativa is turning yellow

    they turn yellow as the plant uses up the chlorophyll and nitrogen in the lower parts of the plant ... normally, nitrogen isn't added in flowering (it is said to actually impede flowering) ... most flowering-type nutrients have at least some nitrogen in them, anyway ... I wouldn't worry about it, unless the plant takes an obvious turn for the worse ... with a sativa, you could still have a long way to go (my Willie Nelsons went 14 weeks, and could have used a couple more) ... :smokin:

    sativa is turning yellow

    That's too early for a sativa to be yellowing.
    Get your pH down in the 6.5-6.8 range and mix in a very small (like 1/4 the recommended dosage) amount of fish emulsion into your next feeding to slow down the yellowing. Or a half-strength 'grow' fert for one of two waterings. You want to see the leaves turning yellow about 2-3 weeks before harvest at teh earliest; the last week only is much better.
