OK here's the scoop, few months back I was checking out some smaller veg plants and I could've sworn their little leaves were vibrating. I just sort of explained it off as being wind current. Then on another occasion during a completely different veg I seen it happen again. I was just in my veg room and lo and behold i seen it happening again, this time it was unmistakable because these plants have some very broad leaves for their size. Not all leaves were vibrating, just a couple leaves on a couple plants. Has anyone else ever seen this happening before?
