    Default Yellowing of leaves 3 weeks into flower

    Hi people,

    I am 3 weeks into flower with a little vannilla kush & a super lemon haze.I have been using GHE Bio Sevia Bloom and westlands multi with john innes, and also a mix of perlite and wormcasts.Things have been going well but the older leaves are now yellowing from the bottom up on both plants . The new leaves are fine and the buds are also looking good .is this anything to worry about ?.My temps have been good and i am also using a 400hps.

    Cheers in advance.

    Nitrogen deficiency. Increase your feeds.

    or it could be a low light thing if the plants are big.

    increase the concentrations. increase the amount of food you put into the water.

    Hi steggs, if they are 3 weeks into flower I would not give them too much nitrogen, a little shoud do no harm, it's normal for the lower fan leaves to yellow when 3 weeks into flowering.

    that depends on the size of the plants and the light quality of the space. it's normal for plants to drop leaves all the time if those leaves do not have access to light.

    I wouldn't worry too much as the plant uses up all the goodness in the leaves when in flowering , Jesus you want to see mine.
    You tried your best and you failed miserably. The lesson is 'never try'.

    don't add nitrogen if your flowering has begun! weed needs minimal N for flowering. yellowing of mature leaves from the bottom up is normal! if ALL the leaves begin to yellow then you've got trouble. cheers ...
