Is it ok if the stipules are brown on the tip on marijuana?

Hey, everybody but my stipules turn brown on the tip and idk if thats okay but its in preflower mode i can see where the buds are coming in but those are fine.help please!

need a pic, cause i think your talking about pistils turning brown/red with maturity, but if not then you must be refering to the actual budsites, in which case that could depend on the variety, but without a pic i dont think your gonna get a good answer

okayy i will but no those r too but im talking about the stipules how you can tell its a female or a male. but thats what i was thinking that they were maturing.
