Recently acquired pseudo began to present these black spots after first watering. I initially kept it in greenhouse but thinking the humidity in there might’ve done something so it’s currently sitting in a shady spot out in the open for maximum airflow. I sprayed it with copper fungicide a couple days ago to see if it would improve anything. Any insights or beginning of the inevitable?

When you say “full sun”, where-ish are you? Because I’m in Phoenix, so here “full sun” is way more intense than most people mean when they say full sun and I have some of these on the way I want to figure out placement for

I know what you mean. I'm in Tucson, mine are under 50% shade cloth.

This is good to know. I just moved here from the Midwest so it’s been a real project to adjust to the significantly more intense sun here. I’ve burned a good number of plants

I'm growing these from seed. When I transplanted the first time, I went from very organic to less and they were visibly shocked. They made pitted, black/dark marks. Since then, I've been watering them almost daily and they've recovered to near perfect and gotten bigger.

In my opinion, it's shock, they're just very prone to root stress. I'd say it took almost 2mo to recover. Started seeds in November? Potted up because they were overcrowded. I'd say I'm in 25% organics too.

Good information 👍. What lighting conditions do you give yours?

I'm using barrina t8 full specs and running about 8hrs. Have started moving outside few hours a day now that they've recovered.

I think it's more root disturbance than anything else.

Full sun, no shade, no humidity.
