Coco grow - need some input.

Hi, I am setting a coco grow right now, sensi star from paradise company.

I am going to use warm casting nd bat guano druing veg/flower stage.

I was wondering that even if i have warm casting nd guano, would i be going to need regular hydro nutes like GH nutes?

Do i need ppm/ec meter?. How much guano do i need for entire grow?

I myself am growing coco just cant provide an answer. Im using Bio Canna and there is no need to ph or add anything.
But I would assume You will def need to use nutes eventually. as for the nutes you need i have no clue.

Ight thanks. Going to get GH nutes nd warm/bat shit
