Most often at this point in flowering they get a little deficient in nitrogen.Give them a feeding of extra nitrogen now.

When flowering begins your plants energy goes to the buds and not the leaves...You look at some off the best weed and the leaves are fucked.. Just watch that not TOO rapid.. I also give a veg nute shot at times if I think the yellowing is too fast.. Watch... but leaf lose ...etc is normal.... Luck
