Yellowing on a robust Jack Herer Auto

Jack Herer Auto. Day 61. Soil. Fox farms at 50%.
About a week ago I posted about leaf tips looking burned. It is a plant that has been flourishing from the get go. After hearing it was probably nitrogen, I waited 3 full days before watering again. At this watering I added only FF Big Bloom which says it is only castings and guano. 2 days later I see some heavier yellowing and some purple.. Wonder if things are messed up here now. I water twice a week. One of those has nutes added. It has been so lush until this.
First 3 photos we're taken now.
The last 2 photos are from 2 days ago.
Thank you for any advice here

I think it looks good bud, getting to the end stage. Leaves change

Killer strain though, have some sitting right here. It's a staple in my house. Great medicinal qualities
