You probably have a mg deficiency. That's what usually makes the leaves curl up and get crispy like that. It doesn't kill, but it hurts your yield because you lose the fans. You say you don't see this on the lower leaves, because it starts there and progresses upwards. plants demand for ca and mg skyrockets the first couple weeks of flowering. You see a lot of new growers get into trouble during that period. my .02
Oh, and how old is that bulb in the first couple pix. See how it's blackened at both ends? Probably near the end of its useful life.
