Recommended Fertilizer and Soil

What would you guys recommend for fertilizer and soil. Also if i grew in a clay pot would it be alright? like a growing pot? or should i stick the seed in the ground or does it matter? also if i buy seeds offline does it matter if it doesnt say indoor or outdoor? because i was going to get ak-47 but it doesnt say anything about outdoor/indoor, or should i get the purple outdoor mix because im growing outdoors and it says outdoors

soil: black gold
fert: peters 20-20-20

50% cow manure compost
50% potting soil
it doesn't really matter if it says indoor or outdoor. some plants produce better indoors and some dont.

noooo... not cow manure. That never helps the buds taste good. Use a nutrient enriched soil and mix it with about 4cups perlite (wear a mask!) and water with a good fertaliser. Guano or fish emulsion work well.
