Texture not Drawn on all uv Coordinates

I'm creating a 2D Tilemap based on a procedural mesh.

Each Tile has his own Quad and vertices and are positioned next to each other to create a seamless mesh. The mesh is created successfully. But when i try to assign uv coordinates to reference a part on a texture only the first Quad/Tile gets the Texture.

So far i have noticed that when i create the Quads with room between them they do all render the texture. Can anyone give some inside to why this is happening and what a possible fix might be.

 //Code snip
 MeshData meshData = new MeshData();
 for (int x = 0; x < _ChunkSize; x++) {
     for (int y = 0; y < _ChunkSize; y++) {
         meshData.AddQuad(x, y);
     }
 }
 
 Mesh mesh = new Mesh();
 mesh.name = "ChunkMesh";
 mesh.SetVertices(meshData.Vertices);
 mesh.SetNormals(meshData.Normals);
 mesh.SetUVs(0, meshData.Uvs);
 mesh.SetTriangles(meshData.Triangles,0);
 //end
