Flowering stage soon

Hey guys whats up! I am 2 weeks from flowering I was just wondering if I have to change my nutrients or I can use the same I am for veg ? On the label it has all the stages from seedlings to flowering. And I have to switch my bulbs (fluorescent on top and I plan to put some cfls on the sides) to warmer one ? I only have 2 plants and have 8 fluorescents daylight one. Will it be really necessary to put some cfls on the sides ? Thank you very much guys!

By the way here's a pic of how they grow from my last post.
