I agree with Str8..
I want to add that in most cases if you transplant to larger pots as necessary you may never need to add nutrients as there seems to enough to grow without. In fact, if I add nutes it seems to burn many of my plants. I am experimenting on that now. Essentially for the last year all I used was the FFOF and no nutes. I am experimenting with adding nutes and having burn issues. Again I say transplanting is giving nutes.
