When do pistils generally start turning color?

My plants are halfway through week 6 of flower and this morning 2 of my 4 plants had a few pistils on the very tops turning brown. At first I thought it was great and just the natural progression of things but then I googled it and found a bunch of info claiming it was too early and a sign of imminent doom. I can't really tell how swollen if at all the calyxs are as this is my first go around. I still think it's all normal but wanted some opinions from the RIU gang.

If it helps, plants showed sex a couple weeks before 12/12 and started showing fuzzy pistils around 2nd day after flip. I also just lowered my RH down to 35-40% in the last week and have been messing with my nutes a bit (more bloom, cut out gro GH trio)

What's wrong dude? i see flowers flowering hard! the couple pics i see of the pistils reddening is fine imho. Maybe some will finish before others as is the case with my gardens as well.....just harvest each flower as they become ripe i'd say but overall i wanna say goodjob cause they look great!

I think they are OK but like I said, the internet spooked me with a bunch of doom and gloom so I just wanted to get some real time opinions to make sure.

Dont believe everything you read on the nets. especially when it comes to cannabis...tons of missinfo

so true

I had the same situation a couple of grows ago. Mine show we d browning pisitils around week 4 of flowering. Searched the net and as you it was all dooms day. I figured id been pollinated. In the end it was nothing. Panicked for no reason. Great tield, smoke and nost of all no seed.
