That is okay, they are supposed to turn yellow at this point. Especially with WW I have heard quite often they look totally ill by the time they are finished flowering. I have one variety that is also sativa dominant that looks very sad by the time she is ready to be harvested. It is what you want, all the nitrogen out of the bud, so don't fret too much. At four weeks, just keep feeding her the food you have been using for flower. I personally am not familiar with it. Your plants look very healthy. If you wish them to fill out more and to add wieght to the buds add some blackstrap molasses to what you feed them, even every watering. I use 1 to 2 tablspoon of blackstrap molasses per gallon of water. It makes the buds soooo sticky that when I grind them up to smoke every bit sticks together with resin.....YUMMMY!

Hi Voneg,What is the soil mix they are in and is the PH {7} is that the PH of the water you are feeding them?Like Jangels said in flowering the leavse will turn yellow and dry up and fall off.Is the whole plant yellow/ If you could post a pix of her it is so much easyer to help you with. Peace

I think they look fine for 4 weeks into flower. Personally, if I was worried at that point I would change their chow to what Jangel suggests. I add 1 TBL. Breir Rabbit or Gramdma's Molasses to every gallon of water when not feeding nutes. Feed them plenty to get a good runoff.

The leaves are going to yellow a bit...basically, the plant feels it is dying, therefore pouring everything she's got into her flowering process. That Molasses is a great source of organic cal/mag, plus all kinds of carbs for her. She's love it, and just be sure you give her a good, clean water only flush about 2 weeks before harvest. After that I would feed only plain pH'd water and water/molasses on alternating feedings till harvest.

Might not be the perfect or best way, but it's worked for me in the past just fine..

Gonna be yummy when their done!
