Hey there Boomer , Great grow. I currently have the sour-G in my arsenal. Those leaves on the last page look familiar. My Sour grapes had a bunch necrotic leaves with random marks on them. They sour grape turned very yellow towards the last 4 weeks of flowering also and ended up with similar leaves as you showed before. I cut at the 7-8 week mark but i noticed some nice fall color tint starting to form. Im going 9 weeks next time i think.
