Flowering looks normal? Pest/Disease

Spider mites generally climb to highest point closest to light and start to make their little webs, Spraying foliars can damage pistils too. Every strain will have slight different variations on how quickly they change, Pistil hairs turn from white to orange due to phytochemical changes within the tissue. Triterpenes known as carotenoids are responsible for the vibrant orange colours of a variety of fruits and vegetables, including peppers, oranges, papayas, and carrots. These molecules fulfil numerous functions, including that of colour attractants. Stigmas turn orange so that they stand out to pollinating insects. Orange pistils are a sign that cannabis buds are mature, filled with cannabinoids and terpenes, and ready to harvest. Dark brown colour on the top section of a pistil hair indicates that fertilisation has taken place. After a particular pistillate flower becomes fertilised by male pollen, the stigma has fulfiled its role and begins to die back, turning brown and shrivelled. I'd give her a excellent look over for nut sacks just incase but I wouldn't worry too much, so long as you know you are not starching them with temps it's probably OK.

Does look like heat damage, but lower buds being affected could point to polination. No male flowers in these pictures, but it might pay to inspect all plants very carefully.

Hey 👋 Doesn't look like deficiencies or a fungus or anything like that. I think it will be genetically determined... but you can't say for sure since you don't know exactly what you have in the tent because of the mix pack. I wouldn't rush into anything and just wait to see what happens... but that's just my personal opinion. The lady looks really good overall, best of luck moving forward 👊🍀🖖
