The WW I am growing had hairs that were brown about 3-4 weeks into flower. You really need to check the trich's in order to check for ripeness. I am now 7 weeks into flower and the crystals are so noticeable you don't need a scope to see them. Hell, the seeds were covered in crystals!

I have never grown a strain that had so many crystals. Last night, I was tending to some plants in the back of my closet and when I brushed by the WW, my arms and hands were all sticky. It is amazing the amount of resin this plat produces.
