Some of my tops around the plant (blue cheese) are changing hair color to reddish brown only day 24 of flower is this normal. Most of the tops hairs are white
Not light burn,on lower buds also haven't sprayed anything
yes it's normal. there will slowly be more and more hairs turning brown over the next weeks. As long as most are still white at this point you should be good. Sometimes health problems can cause them to change though i think.
