Running Ozone now, getting a good bump but.......

Running Ozone now, getting a good bump but.......everyday like clockwork when the lights come on the ORP drops for 2 hours then starts to rise again. Is this normal for ORP to do that as lights come on?
I checked every possible coincidence but cant pin anything but lights to it.
this is a snapshot of 4 days in a row. Dips at 10:am everyday.

ORP will move opposite of PH. Compare your PH chart over ORP chart

I did, and they are not connected with PH up and orp down My PH is flat lined at 8.15 9:00am to 8.2 10:00 pm lights out

I had a similar issue previously, it ended up being grounding issues with my T5 lighting. It would literally drop the orp & salinity probe numbers @ the same time, when the lights came on. Its was a loose wire @ the ballast for ground.

Could you feel the current in the water or no human detection at all? Only detected by voltage meter ?

Nah I didnt feel anything in the water per say but I did get kissed by electrons with a damp hand and bumping it around in my canopy. Thats when I realized something wasn't right and the troubleshooting began.
