They look normal to me. Based on 2 weeks from the time you germed them. The first few weeks are important b/c that is when your roots develop and w/o good roots you can't get a good plant. MJ grows in cycles or spurts in my experience. First 2-3 weeks, root growth. Next 2-4 weeks, veg growth. Switch to flower, 2-4 weeks of stretch and then maturity.
