I noticed you don't have drain holes in your starter cups. They will help you avoid root rot via over-watering.
Because you went straight from a starter cup to a big pot you will waste weeks waiting for substantial growth. The greenery will not grow much until the roots hit the bottom or side of the huge pot. That is why we like to use intermediate pots between the cups and the finishing pot. I use 7 inch square berry pots after TP'ing from cups. Roots bottom out quickly and that tells the pot to start vegging.
Your seedling may toothpick (long skinny main stem) so have a brace made up ahead of time to support the plant and place it just below thw first node. It is too easy to water a toothpick and watch the plant collapse.
Good luck, BigSteve.
