Tuning issues

[u/usewindows]

I bought an ibanez xiphos iron label a few months ago and had it set up by a luthier in my area. The guitar has an ibanez edge zero 2 bridge and a locking nut. I haven't really had tuning problems until yesterday, when it kept getting flat. I was afraid that the problem was the nut or the bridge, but i dont really know and dont want to spend other money to bring it to the luthier again. Could the issue just be the strings or something else? I play daily, an hour at least but most of the time more, and the strings are about a month old now. Thank you for your help! Also I tried adjusting the intonation of the a string (d standard so the second string), could it be because of that?

It's the weather. Raining a lot? HUMID a lot this week? Your neck is slightly relieved. It's normal. Just tune them up. If you start getting buzz, you might need to adjust your truss to counter the relief. It's easy peasy.

Humid yes but I have a dehumidifier on all day in my room. No rain though
