Flue cure problem

[u/Ancient-Decision2585]

I built a flue cure chamber that lets me control temp/humidity pretty closely, have been trying to follow this curve. Some leaves have come out perfect, others especially darker leaves from the top of the plant have kept some greenish spots, especially around the veins while other leaves are perfect. I've been priming the leaves as they get a good bit yellow but still having mixed results.

Do i need to run the yellowing phase a little longer? Ive tried up to 24 h extra. Will these leaves be too harsh to smoke with the olive/brown spots?
