ScrOG-ing. should i do it, or is it too late ?

Hi,I'm pretty new to growing and i think I'm getting on ok. however my plants are now in there second week of flower and they are starting to fight with each other and the tent for space. I have seen ScrOG-ing can give each cola its own little space and can maximise the efficiency of the plant, but am i now too far gone to apply this method? also how are they looking? ps dont worry about the wee guy on the right he is apparently a fast auto-flowering strain i wanted to experiment with.

second week of flower, it's too late.
