No not 2 days, sorry I think I didn't explain it well, I have reppoted both the Elms at same day, three weeks ago.
The fact is that the bigger Elm is showing grow and the smaller don't.
I don't properly expect "results", my main concern is to know if it can be considered "normal" the fact that the other Elm don't have any grow like the bigger one.
I am also saying this because they both seem to develop the same behaviour here, like start grow phase at same time. That's why it seems strange to me this "different" behaviour, different clock
