Good luck with the timing...
I cant remember if you are growin in or outdoors, or how big your plants are.
I grow outdoors, and so I often need to harvest a single plant in stages, as some of the plants are quite large and developed. Take down all the major colas first and anything that the scope tells me is done to my liking. I then open up the plant by tying down some of the intermediate branches to spread her out and let the smaller buds that are not as fully developed ripen. The girls look pretty butchered at this stage but I will sometimes let them go another week or more before I chop the whole plant down.
Typically I have several plants growing of the same strain, and many times I will harvest individual plants in stages to get the trichs at various stages so I can get a mix of highs.
