I bought a new bottle trap for under the sink, there is the tiniest of
leaks, maybe about a couple tablespoons overnight, its coming from the
bottom part (the trap) that screws on to the top part, I have tried
tightening a bit more but still drips.
Any ideas to seal it 100%, although to be honest I cant understand why it
leaks.

Likely not made properly, there is a crack or roughness where the O ring
goes.
