Noob here....

Was wondering how you guys make the switch from heavy P to K. Is it best to use time in flower or is it when the plant starts to show a K deficiency or do u monitor trichomes?

I have 3 grows under my belt and im currently growing a bluedream plant but this is something that i don't quiet understand.

Thank you for your help/ wisdom !

posted my current BD grow. Sun will be 5 weeks in flower.
