If it's just a few leaves here and there I would say it is dew. With high temps during the day the air can hold lots of water but as tep drops it causes water to condense, thus dew. I find it happens more often on the mid to top leaves, especially is another leaf falls across it.
Chronic Chrissy Reviewed by Chronic Chrissy on . Weird substance on leave Woke up this morning and on a couple of the leaves there was this water looking substance. There was no smell to it. It looked as if you sprayed the leaves it would be like left over water just standing but it was only on a couple of the leaves towards the top. I am in day 39 veg fixen to go to 12/12 on day 40. Any ideas what this substance might be. Do leaves bleed out anything? I am stumped. Plants look great. Peace Rating: 5
