Weak and watery are not the same complaint. One is about ratio, the other about extraction.

If it tastes weak but balanced

Use more coffee. Move from 1:17 toward 1:15.

If it tastes weak and sour

You are under-extracting. Grind finer and raise the water temperature before adding coffee.

Frequently Asked Questions

Should I just add less water?+

Yes, that is the same correction as adding more coffee — it changes the ratio.
