Pre flower stigma browning

Greenthumbgrower1986 · Nov 2, 2023

Hi all currently have 3 auto cheese around day 28 now and I noticed on one of the plants 2 of the stigma are browning. Does this mean she has been pollenated? There in 15l pots, under 200w led at 75%, temps between 24°c and 27°c and rh around 55% on a 20/4 cycle. Any one know why this is happening?

I think you mean pistils.

Totally normal, the preflower pistils will turn brown and wither away before the true buds form, it doesn't necessarily mean that it has been pollinated. And, the calyx doesn't seem swollen at all.

They were actually correct from a botany stand point.

"Stigmas are the vibrant, hair-like strands that are found on the pistil. The purpose of the stigma is to collect pollen from male cannabis plants. The stigmas change color throughout a plant’s maturation, starting with white coloration and darkening over time, turning the stigma yellow, orange, brown, and red. "

I totally agree with both these posts.
