A small update here, added a 10UVB lamp in my grow room for some extra crystals, the results could be seen the next day! The next day a few of the leaves were literally swarming with small crystals. (the plant had none)
I am running them full power now, cheating a little on the nute table (adding a little more than I should :P) and they seem to be responding fine. They stretched to 70 CM now and I can fairly say that even though they are in late flowering they are still stretching 1-3 CM a day. I've been trimming them ferociously lately due to lack of space and light not reaching lower bud nodes.
The plant didn't show any stunted growth pattern and it stretched 3 CM that same night so i can fairly say that i got lucky on what leaves to take away
I would love some second opinion though, here are a few pictures and please don't hesitate to point out mistakes in pruning :P (you can just compare these pictures to the ones I sent in a few days back)

PS. Zoom in on pic 5, looks really delicious :P
