Diesel auto

Starting week 8. Flowers are getting bigger and thick. The smell is still weak which it's good for me. Temperature are going up but she doesn't seem to suffer ( just some leaves are curving down on the edge) Feeding her only with flowering nutrients this week. She's loosing a lot of leaves, maybe I've switched to flower nutrients too early. Anyway I added a little bit of veg nutrients today (day 54). Necrosis appeared on two leaves after they get pale. Nitrogen deficiency??
