On this week I was absent for two days, and after I was back, the plant started blooming already)) It showed the black color of the stain on the flowers and on leaves around them - so beautiful!! Exactly what I expected at the exact expected time))) Nice job, FastBuds! Half of the plant is still vegging, but I think it will be not for quite long - talking about hours or something for them to start blooming.
Therefore I changed the nutrients' feeding and released all bondages of lst in order for the plant to feel free for a certain period of time)
