hi all, my original plant is getting close.

she's been in 12/12 for about 7-8 weeks and the hairs on the top colas are starting to turn a rust/brown color. the ones near the bottom are still bright white.

how much long would you think i have till harvest? and how much more growth will there be...basically if it won't grow all that much more over the next 2 weeks can i just harvest her today....it's 420 after all.
