Normal or is this plant dying quick?

You still need nitrogen in flowering. Just less of it. It dont look like your buds are close enough to done yet for the plant to be yellowing like that. They usually yellow like that towards the end of there life like the trees do in the fall. But usually the buds look done when the plant is doing this. So I'd say lacking nitrogen bud.

No it's not an auto, it's a clone

Looks normal, is it an auto?

The nube answer would be to up your nutes, but runoff will tell you exactly which ones D

If you want to know what's going on then you need to check your runoff ph and ec levels, that is your sure way of knowing where your at. High ec, low ec, ph out of whack. This is how you examine your girls before treatment. Cheers friend
