Hold your breath...and relax...
Buds are just growing great, , nice and compact with a lot of crystal forming all over them.
The bambine are slightly purple, I think cool😎, but it made me also wonder.
After speaking with Sangoma and some research , I came to the conclusion that probably it was caused by the drop of temperature in the grow room.
Luckily ,apart from color ,this is not affecting the bambine.
