Growing outside you'll need an IPM. (invasive pest management)
Green Cure for the Powdery Mildew

BT for the caterpillars.

Bug zapper to limit the moths that are the source of your caterpillars. AKA Bud worms. Look them up. Read on them and understand your enemy. They can decimate your crop without you knowing it until harvest.
I spray with both once a week every week right up to harvest.

My yard was long naturalized with plenty of predator insects like praying mantis and ladybugs so PM and catties are all I need to treat for. Nothing else seems to get much of a foothold before a predator comes along to eat them.

Unless you plan on blacking out the windows you'll have to grow in tents. For lights I'd recommend quantum boards. A build with four qb 96 elite v2's would be perfect for each 4x4 space.

 

Your two current outside plants are at extreme risk. Either treat them or pull and throw away today as odds are they will be trash come mid Oct when you try and harvest them.
I threw away over 5 pounds of caterpillar infested buds my first outside grow as I didn't know that critical bit of information.
Once trimmed and hung to dry the caterpillars started to crawl out and hang from silk. Just a few dozen at first. Hundreds 2 days later. Thousands by the end of the week. When broken down it was all full of caterpillar crap and every dot of shit formed a blob of mold. I threw it all away as there was no way to clean or use it.

Moths in your porch light = caterpillars in your cannabis.
