You shouldn't need to use any fertilizer for a little while still. Soils that are prefertilized, and soils you fertilize yourself, generally have plenty enough nutrients to get the plant well into veg without the need for added nutrients. I've used Alaskan fish emulsion, and still occasionally do use it, but I never have the need to use any until after the first month.

It'll be much more suitable when you move everything outdoors, and the plants will sucking up as much Nitrogen as they can get.
Mr. Clandestine Reviewed by Mr. Clandestine on . Another Nute Question... I'm about 2 weeks into my 2nd grow, my first (gonna be) outdoor grow. My girls are about 2/12 weeks in, and I'm about to start giving nutrients, Alasklan Fish Fertilizer, which is 5-1-1. I've mixed it to 1 TBS/gal. I am currently using MG potting soil, since it worked fine for me during my first grow. Im thinking this will be ok for veg? I havent used nutrients before, and I haven't really researched any specifics on nutes/fertilizers, so I was wondering, is this a good start for nutes Rating: 5
