First timer looking for harvest advice.

I've noticed that the top cola hairs have receded quite a bit. I might cut tomorrow.

I am having a similar problem, I am chopping now 50 days into flower because of a small spidermite army was building......
my trichs are 50% milky/ clear......
Im really suprised because it looks finished now at 50 days.....But not to worry at this stage of the game the weed is all good......
Infact as i said i prefer more of a high head stoned anyways....
Good luck pal.....
