Hi mate, best to check all the usual, ph and ec first, then your root condition. looks like a couple of things but probably caused by something else....find the something else. Good luck

Sénescence ou manque d'azote en phase de floraison.Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏Leaves. Color - Yellow

Rate the Bud - 6 Week completed floweringSo this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning.
On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?Buds. Not fattening

Cut off yellow leaves.Can I cut off these leaves?
I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.Week 5

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8a year ago
