would anyone bother trimming off the yellow fan leaves or just leave them? I have no issues with space or airflow - plus I kinda like the colours they have right now as they are getting near harvest time
Sure, take out all these yellow leaves, they already did what they could/should.
More energy will be directed to flower, and more light penetration will impulse the flowering!
you dont have to but i personally pluck them off with the petioles as well. a single downward motion breaks it clean off from the mainstem. i do it because dead plant matter is a breeding ground for fungi and i dont risk it indoors.
