Your plant is wanting more potassium. I been watching my plants when they do this. I add more potassium to diet it stops. Easy on nitrogen as well. I see from leaf in back ground it is getting on high side. Low nitrogen levels in flowering is best. Good luck 🌱
Looking a little mutated to me, from the other photos in your diary I'd guess its from over watering.
Maybe some signs of excess N, may want to ease up on nitrogen fertilizer.
Good Luck!
