its like 3 weeks old, its in a good size pot, the yellowish is in the inner part of the leafes, like in the main vein, the curl is downwards, but dosnt look like overwaterd, i think its about the nutrients, im not sure if its too much or too less, or if i am underwatering it...

since some edges of some leafes are dry, and the very tips of the leafs are drying out too...
