Pistills Dark Pre Flower

those aren't pre-flowers but that's irrelevant. foliar spray or wind, but i've never seen wind cause something so severe, lol... foliar sprays are 100% unnecessary and more akin to masturbation if there is not a direct cause to use one. they have their place but routie use without a reasoson is not one of them. too much light can singe pistils, too, but they turn into little yellow nubs, not change color like this. That's not a normal 'rusty' color transformation so i don't think it is caused from pollination either. Is this the alien moonrocks plants? what the hell happened the last few days? LOL, i'd look at recent behaviour.
