Clutch help pedal hard as a rock.

south

Ok so here’s a rundown of the setup i am running for reference.
I have an action stage 3 clutch with the upgraded Hd internal slave, Brand new zspeed clutch hose, with a brand new master cylinder. Everything from the master cylinder down to the clutch, tranny, hose, and the csc tube is brand new. My clutch fluid always go black for some reason and im wondering if this has anything to do with my dilemma. So i warmed the car up drove it and then all of a sudden i go to shift at abour 5k rpms and then the pedal gets really stiff like super hard. It still does shift into gear 1st and 2nd gear. It goes into gears fine shifting but the pedal just gets stiff and it has a sort of whine to it when i depress the clutch. Also theres a somewhat clicking noise when i let off at the grabbing point. Wondering if anyone else has had this problem and what the solution was. I described the problem to the best of my ability lol just need some help. The tranny is already dropped. No pieces fell out or anything everything seems intact. But the csc has some noise when i spin it almost like a bearing noise. Any help is appreciated thank you!
