I agree with this and also watch calyx swell.Pistils redden prematurely die to genetics, or in low humidity or high heat. Trichomes are what count. Get a microscope for accurately gauging harvest
Yeah 1 other. Looks ok .Just let it grow, if it was pollinated you will know. Do you have other plants? They would have been pollinated too, so if you have others and they aren't effected you are good. I highly doubt it's pollination.
Indeed they've had a rough life. My grow tent will be here tomorrow, it's hard to grow these without control. Light control, down pours, heat draughts. I live in Fl. This winter will be way better , for my next grow.After looking at the pics again I think the cause is environmental. I saw some hairs that just the tips are brown. Perhaps a temperature or humidity drop?
Bingo!LESS is truly more in this art.
