Completed White widows

[Michael 14]

I'm a newbie. First grow. The pictures are white widows in the 8th week. They are in fox farms soil. Been using AN base nutrients. Ac infinity 4x4 grow tent. Ion board 450watt. Running at 55% humidity , 77 degrees at 1.6 vpd. The trichomes are getting milky some. The pistils are getting brown. Are they ready to cut you all think. They look good to go to me but, im not sure.
