Papa_Tanswered grow question 4y ago I mean mouse is right there’s not much information.
However if there aren’t enough nutrients in soil near the end the plant will consume her leaves and it’s completely normal as long as your flower is still developing as it should.
If it’s not looking super sad, has pests or a pathogen, I don’t stress about a few fan leaves dying off.
Really without proper info it’s all just stabbing in the dark as to why your leaves be yellow.
