quick ? please help!

Hey im at day 75 of flowering. My plant is sativa from bagseed. im growing under CFL's which on some bud sites is doing pretty decent. Within the last few days im noticing that the tips of several branches look like they are losing the bud that had developed. can neone tell me why and what i can do.

its like the whole branch is losing density in the buds. and like i said the top 4 inches or so has lost everything. im not sure i was thinking it was just new growth but i dont think so cuz the rest of the buds are losing density.

thanks for any tips

is there another smoker in the house,lolj/k.never heard of that.do u have a before and after pic?

I was thinking this seemed to happen right after i gave some nutes a couple days ago...idk maybe its new growth but if anyone has heard of this lemm know please

Most plants finish flowering between 58-62 days

i know but sativas can take a lil longer. the hairs are still at least 50% if not more white and not amber
