Thanks buddy, buying a microscope now. It's sucks that breeder can't state the exact flower time. So will just go on giving her nuts until it's time to chop them down.
How do you determin when it's time to flush?
The WW I've worked with can flower a very long time and quality improves as it gets older. It resins up early, and the nugs become dense early too, so the choice of when to pick is rather wide. Because of the potential for long flowering, it's easy to let WW run out of nutes, or 'flush' if you like. You can get some very pretty fall foliage colors and associated flavors. Here's a pic of some nice colors on my WW remix, "White Wizard".
