Critical kush auto Barneys farm day 102

[MeLtZ]

Hello everyone I'm new too growing and when I purchased my grow equipment I was given a free seed with my order its barneys farm critical kush autoflower but would appreciate some help as its now on 102 days since seedling and started flowering about 8 weeks ago it was very stubborn and was vegging for 7 weeks but I did stress it a few times which could have stunted it completely my fault as the temps and humidity were to high at 32 degrees celsius but I didn't know at the time until I got a thermometer and hygrometer but since regulating temps everything has been going fairly well I think I just would love some feedback and am very unsure about when to harvest as I find it very hard to determine trichome colour I will post some pictures and would appreciate any help thanks all for your time
