Hello,my first DWC grow my 2 plants are 5 weeks old. My plants leaves look like leaking water drops on the edge of the leaf

I have seen the drops the last 2 mornings. Anyone seen this?? I went away after the lights came back

It was first thing this morning and it was very humid. I just got a dehumidifier hooked up. It went away, will try to get a picture next time.

Got pics
