I seen your plants just now, wow exploded!! They look amazingly good, peak health.
May I say something brother;
I grow outdoors bro every year. In pots and ground, in backyards, hill tops in the bush, raised beds, permaculture whatever you throw at me I will grow it outdoors.
Everything you are experiencing is normal. Grasshopper bite on the fans, spiders eat caterpillars and aphids. Ladybug are your friends always and they come in multiple colors. If you have 2, 3 or 10 they are all friends doing the work for you.
I would not spray anything on my plants that’s going to cause all the fauna to leave. Neem helps with some things it doesn’t do miracles.
Staying on top of the plants health is what counts when outdoors. If you want to stay on the safe side I would highly recommend spacing out the inside of your plant. Pest and disease will start where you can’t see them, the weakest link in your plant.
Right now from my point of view you got stunning incredibly healthy plant. In a month from now when buds set and start packing the real challenge will start.
Try to have some sort of way to space out branches so air can flow thru the inside. And if you see a caterpillar just use your fingers and take it off… after they eat they hide under the leaf. Check under the leaf for evidence of pest. Slugs eat too at night and hide under the pot.
Anyways; I know you didn’t ask me for my advice or opinion. But if you growing outdoors… take some advice from the people actually growing outdoors. Indoor tricks don’t work the same in outdoors game.
