Morning. You're looking great! Don't worry, we all think our plants are slow. The whole "patience" game is hard. But you have some true leaves on all 3 strains, and they look green and healthy. They don't look like they're stretching so that's good. You've got a fairly strong light and have 24 hours of it...sometimes these things might be intense for a seedling but if you don't see any discoloration or wilting...you're probably good. ✌️ keep it up, you'll see growth every week, keep your measuring stick handy and you'll see.😊👍
