hey there Gnugs, the point is the plant is like a rocket , as it lifts off it goes slow at first then faster and faster. germination and so on that's like lift off, then veg is the first bit of the rocket shot with most of the action happening under the soil, right now you're at the point where the acceleration is just about to start. week 5 is when it's gonna start then it goes for like 2 weeks. So you're just about right timing wise. dont stress. Hope this helps ! 🚀
