That looks like some pretty clear N deficiency to me..
hopefully some other folks with more experience will chime in..
If it’s an autoflower, it is often said not to let up on the nitrogen as they enter flower as you would with a photoperiod plant.

Yellowing leavesHi Growmies, im in week 7 of my flowering cycle, my leaves have started yellowing between the veins before turning brown and dying from the tip inwards. Is this a calcium deficiency? Or is it natural dying from the end of flowering cycle or something else? Please advise thanks ✌️Week 16
