First bug is a 'stink bug'...not sure of exact name. Green caterpillar thing looks very similar to a "cabbage looper". Basically it eats leafy greens...cabbage, grasses, pot leaves. Even if it's not a "cabbage looper", it still does the same things...eats leaves. Last thing is def some kind of mite web. Might be spidermite...might not be. But I'm about 99% sure its a mite of some kind...which is no bueno. It's been said that once mites have started an infestation, then its an uphill battle against them the rest of the way. The best way to combat pests is not when they show up, but beforehand. This means have ur predators, insecticides (if using), and other preventative measures in play and on hand before there's ever a problem. Good predators seem to be bugs that eat other bugs...but not so much plant material. Examples would be ladybugs (or their japanese beetle counterparts), praying mantis, and some people swear by catching spiders...like real spiders around the house, not mites...and then relocating them to the grow site. I've also read opinions that very healthy plants with high brix levels seem to not be as affected or as damaged by pests. That part supposedly centers around a belief that a weaker plant exudes some type of signal to the pests that there's an easy meal there. And conversely the supposed theory is that healthy plants with high brix levels somehow magically seem to "ward off" some common pests. But I, personally, don't know jack about much of any of that. I'm workin on my first outdoor grow now so perhaps someone with more exp will weigh in on the subject and either confirm or deny my advices.
