In the spirit of sharing with Keith we all have the same holes on fan leaves. Third photo grasshopper on the fan leaf. I personally don’t spray to kill. I spray to prevent them to even staying around for long. It’s a thing of the plant some get eaten by grasshopper others by caterpillars… I don’t see them later in September.
By the way it’s great to know you grow outside too, I thought you put plants in and out.
I grow a completely different way, biodynamic gardening. Every single insect is telling something about the plant and the environment around it. The plants I leave out in the bush don’t show this kind of damage, which in the greater vision of the growing process one mulched fan leaf is nothing for a plant that’s going to be 6 ft tall and give 3/4 to a lb of bud.
Don’t get me wrong, I’m a killer of slugs, spiders, caterpillars, grasshoppers, aphids, spores… sometimes we don’t need to drop the atomic bomb to kill a spider.
