If it’s your first time growing I would start them out in something very mild with low ferts added. Then transplant after about 3 weeks or so into larger pots like 3gal or bigger. I would recommend something like fox farm ocean forest which already has everything you need already add except for extra perlite which is cheap. Using this method you will have no need for added nutrients until late flower.
You could also use pro mix soil which is also peat based mix but then you would have to add nutrients and perlite. I would recommend not messing with nutrients on your first grow as it’s a common issue for new growers to overwater and over do nutrients and burn plants.
