Dying in Flower

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.

OOO you are a Devious One!

To the best of my understanding, the average reasons why leaves would die off in week 6 or 7 would not have to do with contagions in terms of disease. I would like to assume you have pests under control at this point, however the dying of the leaves maybe replaceable in other plants based off my theoretical estimation that it is caused by user error in the substrate, be it PH or nutrient in nature. Honestly though there is not enough information here to answer your question, no diary linked or photos. So anything anyone says is garbage. Leaves dying off could be any of the following: nutrient burn/deficiencies? disease? pests? heat stress? PH issues? high/low salts? RH issues? Also to phrase it as a hypothetical is not logical. It either is or is not happening. Best of luck
