question bout Nutes?

Hey i've been growing three plants for the last month(April 15) and i recently switched to the flowering stage.(12/12) I just wanted to know when to start it on the nutes cause i really dont know when they should be feed. And also what kind of Nutes to feed them.

Thanx

Well now that you are in flower mode I would look for some type of Bloom nutrient mixture.
