Gorilla Bomb, outdoor grow, directly in soil, Miracle Gro 20-20-20 once per week. In the past few days, leaves have developed brown to black spots that start at edges and spread inward. I have 1 Green Crack under identical conditions and another GB and GC in outdoor pots

You got some yellowing and leaf crawling too. Cut back on that gro, go light on it. Just water them for a week, there in soil so you’ll be fine. I would also start ph balancing your water, go easy on that gro. Good luck.

I've got 3 other plants under the same conditions that are the picture of health, wouldn't they also show similar leaf damage if it's a nutrient imbalance?

That's a pH balance problem 100%. The soil it's in needs to be adjusted. Start ph balancing your water to 6.2 for every feeding or watering.

Nutrition inbalance. Vegging requires a ratio of 3-1-2 npk. Flowering is 1-2-3 ratio. Probably has the soil ph out of alignment too. Would be worth looking into as well
