The plant is producing small sized buds (they still have to mature 2-3 weeks) but full of trichomes so I'm still happy with it. This plant growth was pretty slow and so is the flowering stage, I think I've got an unlucky seed and this, combined with the fact that I accidentally decapitated her, didn't let the plant show her full potential.
I'm growing another plant(same genetics) next to it without any training; it's 75 cm tall and it grows much more faster than this plant, it is already flowering at DAY 45 and it's really impressing me.
