Somethings wrong! HELP

My baby is about 4 months old, and just hit 5 feet, shes aprox. one week into flowering.

The second lowest branch suddenly started drooping and it looks like it is drying but its still grenen.

I cant take pictures today its getting dark, will tomorrow. it is only this one branch but im concerned, the branch is about 6-7 inches long.

please help!

serously.. noone knows?

Need some pics that would help. Maybe something is eating it

also on 2 or 3 of the fan leaves there is a white spot..? i dont know what thats from either.

the white can be caused by either Ph is changing with every watering, or your not letting your water sit for 24 hours to dechlorinate (BIGGIE). if you move your plants inside you'll find it much more rewarding in quality, as you control more. what kind of nutes do you use?

so the branch was broken.. i pulled it off with little to no effort. I dont think it will affect much right? other than that my plants healthy, one or two yollow leaves but thats normal durring flowering.
