Might need some more N-def, if yellowing underneath. At top could be other things, though. Ensure pH is proper. It's a false narrative that you need to greatly reduce N in flower phase. the plant needs plenty of N to build buds too. 120-130ppm N, if you calculate from guaranteed analysis labels. (cumulative total)

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 🙏

Yellow Cotyledons?NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?
