Toxic Sweat?

I've been trying to get answers to a problem I'm having with burnt-looking leaves. Janet 3.jpg I haven't fed or watered since Monday.So, I go in to check on my girls when the lights came on this morning and I found a liquid sitting on a leaf. It looked like water, but wasn't evaporating - and it's right by the fan. It had an oily feel to it and smelled like, well, herb. Is this plant perspiring nutes out of the leaf, which in turn causes the burn? If so, is this caused by lockout due to PH?

Yes, I do. I have an oscillating fan - and this plant is right next to it. It gets most of the air.
