    Yea there is a long list of shit that can cause yellowing, we need pictures.
    and dont cut the leafs off, the plant can use whats stored inside of it.

    If it were the 8th-10th week of flower, then it would mean your plant is nearing completion.

    4th week is a lot more difficult to diagnose w/o photographs.

    Agreed. Too soon for the yellowing associated with natural apoptosis in late flower. I think we can rule that out.

    I'm gonna shoot from the hip with no pictures it's hard to be sure. Whats your N in your bloom mix. leafs yellowing from the outside in if so its MOST likely a Nitrogen def. They are using a lot of energy to Grow those buds. This is the most common reason for yellowing. BUT again we NEED pictures to tell for sure. GL Happy Growing Jay

    The first photo you posted says it all. It's a N deficiency. I was thinking Sulfur def until I seen the photos. Up your N if you've been using it, if you haven't then start using it at 1/4 strength.

    Bloom nutes aren't heavy at all in N, normally you'll find that in your veg nutes. check the values x-x-x the first x is your nitrogen.
