Questions about fertilizer @ Outdoor Grow

will b growing outside this year. will be digging 2x2 holes and replacing the old soil with Pro Mix-Organic Mix..

what nutes shud i buy for the veg cycle.. right now i just ordered some superthrive, and plan on buying alaskan fish fertilizer 5-1-1... do i need anything else? When can i start to add the superthrive and fish fertilizer to the plants.. and what recipe/schedule should i use with the nutes?...the seedlings just sprouted today

also what strength shud i use the nutes at?? i read you need to dilute it 1/2 or even 1/4 of what is says on the label.......
