I only have one plant that looks like this. I've looked for bugs and there are none. The plant has gone through a bit of stress however. It was in 90+ temps for a day or too, has been slightly over watered, and I think it was under too much light. With that said the other plants are totally fine, and this plant is absolutely the runt of the 3 Sent from my Pixel XL using Grasscity Forum mobile app
I think it just genetics. I have one plant that has the same thing on its leaf. But I'm not worried about it. Mine look healthy otherwise and so does yours. My last grow, the runt ended up with the most and biggest buds. So I wouldn't worry about that either Sent from my LG-H830 using Tapatalk
It got hot and dry here this summer. I had the same thing on one plant, and it turned out to be leaf hoppers. They come and go, but not before sucking on your leaves. Didn't effect any buds though. Sent from my iPhone using Grasscity Forum
