My grow isn't outside (as I'm guessing yours is since you said it hasn't rained), but when my indica was put into flower, the first week or so she would "weep" moisture. It was the oddest thing, as I knew I wasn't getting any water on the leaves. I only noticed it happening at around the time the lights came on. I just carefully blotted up the XS water off the leaves, as the water drops with the light on will burn that leaf in that spot, but other than that I didn't do anything else. By the second week in flower, she stopped doing it. Who knows? It never seemed to have any ill effects.
