COCO COIR Brownish/Gold on leaves plant is bent over

[Redempt]

There is a brownish/Gold color on the leaves. I’m not sure what is is and how to get rid of it. I have healthy buds as of now but I’m worried this will sooner or later ruin my buds. How can I fix this and what is the Brown/Gold color?

You are in late flowering. Your plants have used up all the growing nutes and your fan leaves turn colors like trees do in the fall. It's completely normal. They might fall off. No pun intended.
Someone else look at pictures 2 and 4. Is that WPM?

This grower has another post that you commented on, with definite WPM.
