Thanks everyone, as for soil, I checked it and under the surface is more cold and somewhat humid but not wet; in some spot when planting DLs I added common garden soil, so it's a mix, and it seems clay tends to go tu surface. When I water the water goes under the surface; in some spots it takes few seconds but it never really stays on topo of soil.
Leaves: I checked leaves and took some pic again for help. I think I have rust or leaf streak. I found somehing that looks like rust butit's only on the back of the leaves, anyway if you could help me understand what this could be I'd be happy because I'm really a newbie.
Many thanks!
