I haven't seen that before, but it looks like it could be some sort of leafhopper. They are green around here though but that has the same basic shape. Maybe search what leafhopper insects in your area look like. And in those same pictures it looks like something has been nibbling the leaves.
Watch closer in veg next time. I'm sure those balls have been visible for a while now. Those are some fat stalks though and the plants look healthy, great job either way.
Lol I saw a video where some guy grew a plant start to finish under a 9 watt led strip. But I guess they could have lied about it and had more light, only yielded like 4 grams. But yeah I would have ditched that too, just not worth the effort
Congrats, this was fun to watch. The leaves with sugar on them will do the trick, especially with your low tolerance. Just use a bit more than you would of bud. Most people make hash from it, or cannabutter.
