All looks ok. Seems that they are a little bit slow with their grow.
2nd stage of leaves are fully formed (3 Fingers)
3rd stage of the grow leaves already good visible (the leaves with 5 Fingers)
29-November, update:
Watering is not necessary so far. The bottom of the pot is still damp - checked with an wooden stick (see photos)
This is a good way, to check if the bottom of the pot is still moist and the roots are able to find any water, it's good for roots-growing
1-Dec - update
Watered yesterday. Today the tips are hanging down a bit. Too much water! I'll hold back a bit on watering. Otherwise everything ok.
