When my plants are normally 7"-8" tall I have them in 1 gallon size pots usually until they are larger and ready for transplant into 3 or 5 gallon size pots. If the medium stays wet for too long of time it slows growth, usually I water my plants every 3-4 days. Larger pot sizes than optimal for vegetative stage and growth height can cause slower growth due to the medium staying wet a longer time until the plant develops sufficient size roots and can use the volume of medium. Stagnant air flow with depleted CO2 in the grow area may also slow growth. 7"-8" of growth in 3 weeks from seed is not necessarily a bad growth rate. if you are able to distinguish the branches at the third node clearly to avoid cutting them if wish you may now Top your plants at the third node or wait for 1 more node of growth until you Top your plants if you prefer.
