no what it is is hash tips ,.. or that's what some cannabis author called them. Personally I am not so sold on the idea that it is a ton of trichs, you can watch my youtube video at 1 minute 10 seconds

They are more commun with LEDs, when I got my hash tip though it wasnt because the buds were too close to the light but getting LOTS of light from multiple source ... I looked at it with a microscope and it did look like thousands of trichs but at the same time, I know what bleaching looks like and even though there was no bleach on the leaves around I am pretty sure that it's what it is, bleach.
I bet you grow with LEDs? The key with LEDs is not to try to get the light as close as you can like most people think but instead have the light at the perfect height for a perfect blend of the spectrum without being too far.
that's that. Google ''hash tips'' and you will find an article and many posts on various forums.
EDIT, perfectly fine to smoke it, mine almost vanished during drying because it wasnt as big as yours. I have read people doing side by side blind smoke test and couldnt tell which one was the bleached one.
