Hello, about the water, she’s young and while you keep her in there (probably until she grows 4 leaves) you should just spray them with a recipient, you don’t really need to put much water because she’s young and she don’t need that water yet, then when you change them to other pots (15l, 20l..) you can water a little bit more but not too much and you also want to check that all the dirt is moisty but not overwatered, and then the much she’s get bigger the much she will need water (1l, 1.5l..), and basically is that but if you want to learn more you can always search for better information.
Hope it helps!
Good grow! ✌️🏼🌱
