Any reason to worry?

Last week I watered 600ml and since then the pot feels slightly heavy. Personally I think that it was too much but I also think the roots aren’t so much evolved that they can reach the water that is in the bottom of the pot. After that accident I watered about every two days and just about 100 to 200ml because the top of the pot was pretty dry. Now she looks like this.

1. Do you think that the leaves are concerning the way the tips drop?
2. Is my technique a good way to go slowly let her reach the water in the bottom?

Thank you for your answers :)
