Hi, let’s try to work through your issue step by step. Dark leaves These often appear when the plant is getting too much nitrogen. Please check which of your nutrients contains nitrogen and reduce it as soon as possible. Pistils They look normal. This slight brown coloring can actually be caused by the light being too close. Try to keep a distance of 20–30 cm. If you can, measure the PPFD value of your light. The pistils will keep coming back regardless. Spider mites Unfortunately, if you have a problem with them, your harvest is at risk. From my experience, getting rid of them completely is very difficult. Before flowering, you can treat them well with neem oil or a nettle tea spray. You can also try tying a damp cloth to the end of your vacuum hose and carefully vacuuming them off.

I'm in agreeance with Organoman, when just the tips bring it can be caused by pollination. Maybe something internal in the tent, a ball sack hidden away. It can also be caused by touching them or spraying them with things like Ultraviolet said. Mites are a big problem, if they are not kept in check they can decimate a harvest. Its not great treating them in bloom as the chemcials will stay on the buds and inturn you smoke them :( Best option is predator bugs that eat them. Got to knock their population down before they fuck it all up. and after this grow need to kill all the medium in the tent or cook it. and then wipe it all down with something to kill the mites if any are lingering aorund. They will travel to a new plant if not taken care of.

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.
