Small leaves around buds beginning to deform and brown

IMG_0412.jpeg Hi, have been looking for a solution to this in the threads but couldn't find symptoms quite the same as mine. I have 5month old 'dinafem original amnesia' about a week or 2 away from harvest and since yesterday the smallest and highest leaves around the bud heads are getting deformed and rusty coloured from the outside inwards. Nothing has changed below the very top of the plant or in the buds themselves.
Ive slowed down on bloom nutes in the last 2 weeks, and the problem is occurring on every head bud on one plant, about half of the heads on another, and hasnt hit one plant. I have attached pictures of affected buds and one of a healthy looking bud.
Im in the mediterranean and the plant is getting plenty sun and good temps, being a sativa i highly doubt its heat burn, as this plant is adapted for equatorial heat and light. I read that it could be boron deficiency or a calcium deficiency possibly due to a poor PH level.
Please advise me what this could be and what i should do and how dangerous this is to my plants :( thxIMG_5308.jpeg

Boron deficiency. It's only the tips it looks like so likely not bud rot. It appears almost like calcium deficiency except boron affects the newer leaves only or first.
