Very nice plant, you did a great job.
Yes, I also have 4 side shoots that don't catch up.
I should have tied the larger ones further down until the others had clearly caught up with them.
@AcidBurn_40, I tried keeping the canopy flat - and managed to do that successfully during veg, but once the flowering stretch started I didn't have the space to do that as my box is pretty small (60x37x80cm)
