Here is an interesting topic "fox tailing". Ever had this happen? My current grow as shown about shows this condition. Why? I do not know. Researching this it is either 2 things happening (so "they" say) heat or light stress, take your pick. Ever consider it may be possibly genetics as well? I have reduced the amount of light and they are approximately 2 feet above the plants so that kind of eliminates that issue, they are not burnt nor are they stressed out. I have seen pictures on this site which almost look like my current buds so what gives on this topic? Yes, the buds are nice and bulky and covered in trichomes and are progressing towards the final week (12 weeks indoors for sativa, so "they" say) and the hairs are turning more color as expected by waiting another week, they are almost ready!
My room temp is constant 76 degrees, humidity at 45% NO nutrients for the last month, only ph 6.5 water, there is nothing else that could have contributed to this, so I think it's the plants themselves.
What is your experience with this phenomena?
