The time has come to pull the plug on the Blackberries and the Gelato. The 2nd Blackberry which never showed much purple is starting to make a leaf color change like leaves in the fall, not the buds, but the fan leaves. I'm going to flush the Blackberries and Gelato tomorrow and let them dry out and harvest them at that point.
The Sour Diesel's have at least a week to go but probably not much more.
My gelato has the same problem since seedling aswell, just some slight discolored green, but hasn't seemed to affect the grow time, all 3 of my fastbuds started flowering at 21 days
