Can anyone tell me what this is.
The pattern on the leaf makes me think you got water on it and the lights burned the leaf where drops were.
Rust colored spots are often calcium deficiency, although this doens’t look like it to me. @Myfriendis410 what do you see?
Here is a calcium deficiency.
Check the under side of the leaf for pests.
How do you fix your more cal mag???
I guess where I’ve grown outside for so many years never had this problem because the rain added the calcium.
Or you think I should flush and start again??
Looks like splash to me.

I agree with the above. Looks like water/solution splash to me
I haven’t splashed water on any of the leaves.
