Been seeing water droplets on upper leaves

I have been seeing water on the leaves close to the light, how is this possible and what could it be from, is this normal. The tops are atlease 3ft from the res.

It's probably dew.
I see it on some of my leaves especially in the morning right after lights on.

Maybe it is condesation from the humidity.

I have seen it with some of my plants. Plants do sweat and release moisture. I drop here and there is not a problem. If it looks like it just rained you need more airflow and a dehumidifier.
Is your temps on the high side? That can make them release more moisture.
