Nitrogen.. phosphuros.... etc.

at what point in the plants life are ea. of the chemicals most important and vital? for example nitrogen is to be used mainly durring the vegetation stage? what about the rest.... i guess my question is - what chemical is most vital at what point in the plants growth, how much, and how often? What are some things i should NOT do with these 3 primary chemicals. nitrogen, phosphuros, i'm drawing a blank on what the last one is. *brain fart!*
thanks!

you need potash (potassium) for flowering and also some extra phosphorus to help the plant to carry the extra budds. so a high nitrogen feed for vegg and then a high potash feed for flowering.

so do u jus find some nute that have pottash in it highly or bledn up some banannas lol

any high potash fertilizer will have the nutes you need for budding your cannabis plants.

anyone got a brand of fertilizer that they can recommend??

I've used plant gro or mir.gro 20-20-20 for growing. 10-52-10 for budding. I know some people might not agree, cool, but its worked for me for 5 years. like they if it ain't broke don't fix it
