Seedling ?

It may be time for a transplant. Upgrading to a larger pot with fresh soil will give the roots more space and provide the plant with what it needs to thrive. Consider adding some Mycorrhizal fungi during the transplant to promote strong root development and improve nutrient uptake. Focus on the overall health of the newer growth, as that’s the best indicator of how your plant is doing. Once transplanted, the plant should settle in and bounce back quickly. Good luck! 🌿

transplant likely needed. that cell/plug is very small.

*first couple sets of leaves can look fugly.. not just the first set.

These look fine. Yes, they are big enough to warrant a transplant, and it would be wise. The first set of serated leaves and cotys often look fugly and are not a problem as long as newer growth is fine. The cotyledons (first non-serated leaves) will show issues easily. The plant will want to shed them at any hint of nute deficiency. It's a sign you can start fertilziation, too. If this is soil, a transplant adds more amended nutes with the new soil, so i'd wait to see how they react to the new substrate before amping up fertilization. if soilless, you should be fertilizing immediately, anyway. Yellow cotys would indicate that you need to give a bit more. Cotys fade more easily than regular leaves. A plant will shed them even if mostly healthy, otherwise. It doesn't take much for them to show symptoms and may not even require a fertilizer adjustment in some cases.

OUI ,le changement de pot est necessaire .Aucune inquietude sur le petit changement de couleur elle te fait savoir son besoin .Apres le rempotage elle reprendra vite une belle couleur

Yes absolutely she needs a new home as soon as possible. I wouldn’t worry about the leaves yellowing. Transplant and she’ll be fine.
