yellowing at day 31 of 12/12

Here is what is happening now. Any ideas?

its yours what do you think/ I'm not growing it.

nitrogen def.
But you don't need it in the flower cycle.
It will ruin the burn and taste if nitrogen is added this late.

I think I need some other opinions so I joined this site and started posting

Thanks Cannabiscult

Word. If you start adding N the last month or so your product will taste like shit. Just let it run her course.
