will adding phosporus = faster flowering?

so i have my first outdoor grow outside in the woods. they are getting huge right now they are like 3.5-4 feet tall. i started them indoors on like 4/20 and theyve been outside since 05/1. ive been feeding it with organic mexaican bat guano and peruvian seabird guano both are nitrogen. i was wondering if i started hitting it with phosphorus will it start to flower earlier?

no it will flower when the light schedule gets cut back to shorter days. the phosphorus will help with root development though.

thanks i guess i will hit it with a little phosphorus for stronger roots
