My plants are nearing the end of flowering, and the hairs on the bottom buds are orange and red, while only some of the top hairs are turning. should i cut the buds that are ready or wait and keep them going til the whole thing is ready?

You need to check the trics with a 30x scope or higher. If they are done, harvest them. I like to do the whole plant at once.

Usually its the top thats done first. but yea, If you need smoke, cut a few lowers Its not going to hurt anything.

On the other hand if you leave them on you will not hurt anything either. They may even get bigger.

Indoor plants will finish from the top down and outside plants from the bottom up. It could be different with others but this has been my experience.

Sounds like you should keep em going for another week or two. You don't wanna cut too early or else you miss the window of peak-potency. Unfortunately your gonna hear this at EVERY stage of this looong process and that's patience is a virtue I'm not very patient though, so it's pretty hard haha.
