Droplets on my leaves???

I have droplets of something on my leaves. When I touch whatever it is, I find that it is sticky. I don't see any bugs on them... could it be something else?? Please give me your opinions and advice. I attached some pics.
Thank you.

i have also seen droplets on mine...

I have seen leaves leak sap.
But what I have seen regularly is when one leaf is covering another, the upper surface of the lower leaf collects condensation. Your droplets seem to be following the leaf margin to their left. cn

Yes, I'm currently working with white widow. This is my first grow ever and its indoor so I apologize if I am a little clueless. I just wanted to make sure it wasn't aphids. I understand that there is something called aphid dew and I looked it up but didn't think it looked like there were any bugs in or around the droplets. I was thinking about getting a magnifying glass to make sure. I just didn't want to spray any "dishwasher liquid mixture" on it without being sure. I think it might just be sap like you said though. Thanks to those who answered!!! If anyone else can leave their opinions it would be much appreciated.

It may be due to overwatering.
It's sorta like the leafs are sweating out excess moisture.
How are you watering them?

Make sure your ceiling isn't leaking...
