Dry nutrient question

Hello I currently have a small grow going with 5 seedlings in fox farm ocean forest/happy frog soil mixed with perlite. I know I shouldn’t be giving nutrients yet but have the organic pack from homegrown when the time comes. My question is about how to feed the dry nutrients. Just put in the soil or mix with water first and feed? Thanks
