welcome to the forum and congrats on the new tank. Made sure the rhizome of the anubias and the javafern and not burried in the substrate. Consider 50% waterchanges 2 times a week for the first 2 weeks. Also, aim for a lights on period of 6h at the start.
Water well can work but can also have higher nitrates or metal levels. I would not worry very much about it.
And read a lot, be critical of what you read, filter what you learn.
All the best
