Bloom nutrient only?

I was wondering, if im going to put clones directly into flowering, would I just need flower nutes? Like a 0-4-6 (example) Do I need the nitrogen at all? and can someone direct me to a nutrient thread so I can understand the NPK a little better, thanks!

When you clone give them 2 weeks to gain some roots. In that time and 2 weeks into flowering you want to give them Veg nutes which are high in N. (5) Nitrogen gives them leafs, the more leafs the more co2/sun the plant can get to convert into energy.
After 2 weeks into 12/12 you want to switch to bloom nutes so the plant will have P/k which helps set and flower.
